QIAquick PCR Kits are also available in multiwell format for preparation of 8 to 96 samples (see page 33 for ordering information). QIAquick Kits provide high yields of pure nucleic acids, for direct use in applications such as: • Fluorescent and radioactive sequencing • Ligation and transformation • Restriction • Amplification • Labeling • In vitro transcription • Hybridization • Microinjection Enzymatic reaction cleanup using QIAquick Kits The QIAquick system is suitable for fast cleanup of up to 10 ug of DNA fragments from enzymatic reactions and agarose gels (see the QIAquick DNA Cleanup Guide, page 8). Enzyme contamination of DNA samples can interfere with subsequent downstream applications. QIAquick Spin Kits can be used for highly efficient removal of a broad spectrum of enzymes widely used in molecular biology. In addition, QIAGEN offers the new MinElute™ Reaction Cleanup Kit, which is specially designed for fast and easy DNA cleanup from all enzymatic reactions. Using proven microspin technology, the MinElute Reaction Cleanup Kit delivers highly concentrated purified DNA by using an elution volume of only 1 0 ul (see ordering information, page 33).

Special buffers provided with each kit are optimized for efficient recovery of DNA and removal of contaminants in each specific application. DNA adsorbs to the silica-membrane in the presence of high salt while contaminants pass through the column. Impurities are efficiently washed away, and the pure DNA is eluted with Tris buffer or water (see page 17). The QIAquick spin columns offer two handling options — as an alternative to processing the spin columns in a microcentrifuge, they can now also be used on any commercial vacuum manifold with luer connectors, e.g., QIAvac 6S or QIAvac 24 with QIAvac Luer Adapters. Adsorption to QIAquick membrane — salt & pH dependence The QIAquick silica-gel membrane is uniquely adapted to isolate DNA from both aqueous solutions and agarose gels, and up to 10 ug DNA can bind to each QIAquick column. The binding buffers in QIAquick Spin Kits provide the correct salt concentration and pH for adsorption of DNA to the QIAquick membrane. The adsorption of nucleic acids to silica-gel surfaces occurs only in the presence of a high concentration of chaotropic salts (1), which modify the structure of water (2). Adsorption of DNA to silica also depends on pH. Adsorption is typically 95% if the pH is <7.5, and is reduced drastically at higher pH (Figure 1). If the loading mixture pH is >7.5, the optimal pH for DNA binding can be obtained by adding a small volume of 3 M sodium acetate, pH 5.O. 100 ai S 50 a a. < Z o L 2 4 6 8 10 12 14 PH Figure h pH dependence of DNA adsorption to silica. 1 pg of a 2.9 kb DNA fragment was adsorbed at different pHs and eluted with Buffer EB (10 mM Tris-Cl, pH 8.5). The graph shows the percentage of DNA recovery, reflecting the relative adsorption efficiency, versus pH of adsorption. QIAquick Spin Handbook 07/2002 11 Optimized binding buffers for every DNA cleanup task All QIAquick Spin Kits contain identical QIAquick spin columns but different binding buffers optimized for each specific application: • Buffer PB in the QIAquick PCR Purification Kit allows the efficient binding of single- or double-stranded PCR products as small as 1 00 bp and the quantitative (99.5%) removal of primers up to 40 nucleotides. This kit can therefore be used to remove oligo-dT primers after cDNA synthesis or to remove unwanted linkers in cloning experiments. • Buffer PN in the QIAquick Nucleotide Removal Kit promotes the adsorption of both oligonucleotides >17 bases and DNA fragments up to 10 kb to the membrane. • Buffer QG in the QIAquick Gel Extraction Kit solubilizes the agarose gel slice and provides the appropriate conditions for binding of DNA to the silica membrane. All of these buffers are also available separately (see ordering information, page 33). pH indicator in solubilization and binding buffer QG The binding and solubilization buffer QG has been specially optimized for use with the QIAquick silica-gel membrane. Please note that Buffer QG should not be used with QIAEX II silica resin. Buffer QG contains a pH indicator, allowing easy determination of the optimal pH for DNA binding. DNA adsorption requires a pH <7.5, and the pH indicator in Buffer QG appears yellow in this range. If the pH is >7.5, which can occur if the agarose gel electrophoresis buffer is frequently used or incorrectly prepared, the binding mixture turns orange or violet (Figure 2). This means that the pH of the sample exceeds the buffering capacity of Buffer QG and DNA adsorption will be inefficient. In this case, the pH of the binding mixture can easily be corrected by addition of a small volume of 3 M sodium acetate, pH 5.0, before proceeding with the protocol. In addition, the color of the binding mixture allows easy visualization of any unsolubilized agarose, ensuring complete solubilization and maximum yields. The indicator dye does not interfere with DNA binding and is completely removed during the cleanup procedure. Buffer QG does not contain Nal. Residual Nal may be difficult to remove from DNA samples, and reduces the efficiency of subsequent enzymatic reactions such as blunt-end ligation. Optimal pH Figure 2. Indicator dye in solubilization and binding Buffer QG identifies optimal pfi for DNA binding. pH loo high 12 QIAquick Spin Handbook 07/2002 Washing During the DNA adsorption step, unwanted primers and impurities, such as salts, enzymes, unincorporated nucleotides, agarose, dyes, ethidium bromide, oils, and detergents (e.g., DMSO, Tween® 20) do not bind to the silica membrane, but flow through the column. Salts are quantitatively washed away by the ethanol-containing Buffer PE. Any residual Buffer PE, which may interfere with subsequent enzymatic reactions, is removed by an additional centrifugation step. Elution in low-salt solutions Elution efficiency is strongly dependent on the salt concentration and pH of the elution buffer. Contrary to adsorption, elution is most efficient under basic conditions and low salt concentrations. DNA is eluted with 50 or 30 ul of the provided Buffer EB (1 0 mM Tris-CI, pH 8.5), or water. The maximum elution efficiency is achieved between pH 7.0 and 8.5. When using water to elute, make sure that the pH is within this range. In addition, DNA must be stored at -20°C when eluted with water since DNA may degrade in the absence of a buffering agent. Elution with TE (10 mM Tris-CI, 1 mM EDTA, pH 8.0) is possible, but not recommended because EDTA may inhibit subsequent enzymatic reactions. DNA yield and concentration DNA yield depends on the following three factors: the volume of elution buffer, how the buffer is applied to the column, and the incubation time of the buffer on the column. 100-200 ul of elution buffer completely covers the QIAquick membrane, ensuring maximum yield, even when not applied directly to the center of the membrane. Elution with <50 ul requires the buffer to be added directly to the center of the membrane, and if elution is done with the minimum recommended volume of 30 ul, an additional 1 min incubation is required for optimal yield. DNA will be up to 1.7 times more concentrated if the QIAquick column is incubated for 1 min with 30 ul of elution buffer, than if it is eluted in 50 ul without incubation (Figure 3, page 14).

QIAquick Spin Handbook 07/2002 15 Applications using QIAquick purified DNA DNA purified with QIAquick is suitable for any subsequent application, such as restriction, labeling, hybridization, PCR, ligation and transformation, radioactive and fluorescent sequencing, in vitro transcription, or microinjection. For direct sequencing of PCR products, refer to chapter 15.2 of Current Protocols in Molecular Biology, Ausubel, F. M. et al., eds (1991) Wiley Interscience, New York. A critical parameter in sequencing reactions is the template-to-primer ratio. Optimal ratios for radioactive sequencing of PCR fragments are provided in Table 2. Table 2. Optimal molar template-to-primer ratios for manual radioactive sequencing Template:primer Internal primer 1:1 -1:5 PCR primer 1:10-1:20 For automated sequencing, the template-to-primer ratio is also important.

For cleanup of other enzymatic reactions, follow the protocol as described for PCR samples or use the new MinElute Reaction Cleanup Kit. Fragments ranging from 100 bp to 10 kb are purified from primers, nucleotides, polymerases, and salts using QIAquick spin columns in a microcentrifuge. Notes: • Add ethanol (96-1 00%) to Buffer PE before use (see bottle label for volume). • All centrifuge steps are at 13,000 rpm (~1 7,900 x g) in a conventional tabletop microcentrifuge. 1. Add 5 volumes of Buffer PB to 1 volume of the PCR sample and mix. It is not necessary to remove mineral oil or kerosene. For example, add 500 ul of Buffer PB to 1 00 ul PCR sample (not including oil). 2. Place a QIAquick spin column in a provided 2 ml collection tube. 3. To bind DNA, apply the sample to the QIAquick column and centrifuge for 30-60 s. 4. Discard flow-through. Place the QIAquick column back into the same tube. Collection tubes are re-used to reduce plastic waste. 5. To wash, add 0.75 ml Buffer PE to the QIAquick column and centrifuge for 30-60 s. 6. Discard flow-through and place the QIAquick column back in the same tube. Centrifuge the column for an additional 1 min. IMPORTANT: Residual ethanol from Buffer PE will not be completely removed unless the flow-through is discarded before this additional centrifugation. 7. Place QIAquick column in a clean 1.5 ml microcentrifuge tube. 8. To elute DNA, add 50 ul Buffer EB (10 mM Tris-Cl, pH 8.5) or H20 to the center of the QIAquick membrane and centrifuge the column for 1 min. Alternatively, for increased DNA concentration, add 30 ul elution buffer to the center of the QIAquick membrane, let the column stand for 1 min, and then centrifuge. IMPORTANT: Ensure that the elution buffer is dispensed directly onto the QIAquick membrane for complete elution of bound DNA. The average eluate volume is 48 ul from 50 ul elution buffer volume, and 28 ul from 30 ul elution buffer. Elution efficiency is dependent on pH. The maximum elution efficiency is achieved between pH 7.0 and 8.5. When using water, make sure that the pH value is within this range, and store DNA at -20°C as DNA may degrade in the absence of a buffering agent. The purified DNA can also be eluted in TE (10 mM Tris-Cl, 1 mM EDTA, pH 8.0), but the EDTA may inhibit subsequent enzymatic reactions. 18 QIAquick Spin Handbook 07/2002 QIAquick PCR Purification Kit Protocol using a vacuum manifold QIAquick spin columns can now be used on any vacuum manifold with luer connectors, e.g., QIAvac 6S or QIAvac 24 with Luer Adapters. The following protocol is designed to purify single- or double-stranded DNA fragments from PCR and other enzymatic reactions (see page 8). For cleanup of other enzymatic reactions, follow the protocol as described for PCR samples or use the new MinElute Reaction Cleanup Kit. Fragments ranging from 1 00 bp to 10 kb are purified from primers, nucleotides, polymerases and salts using vacuum-driven sample processing. Notes: • Add ethanol (96-1 00%) to Buffer PE before use (see bottle label for volume). • Switch off vacuum between steps to ensure that a consistent, even vacuum is applied during manipulations. 1. Add 5 volumes of Buffer PB to 1 volume of the PCR sample and mix. It is not necessary to remove mineral oil or kerosene. For example, add 500 ul of Buffer PB to 1 00 ul PCR sample (not including oil). 2. Prepare the vacuum manifold and QIAquick columns: QIAvac 24 (see page 30, and Figure 6): • Place the QIAvac 24 lid on top of the QIAvac 24 base. Make sure that the gasket fits tightly in the groove of the QIAvac 24 lid. • Insert up to 24 QIAquick spin columns into the luer extensions of the QIAvac 24. Close unused positions with luer caps and connect QIAvac 24 to a vacuum source. QIAvac 6S manifold (see page 30, and Figure 7): • Open QIAvac 6S lid. Place QIAvac Luer Adapter(s), or blanks to seal unused slots, into the slots of QIAvac top plate, and close the QIAvac 6S lid. Place the waste tray inside the QIAvac base, and place the top plate squarely over the base. Attach the QIAvac 6S to a vacuum source. • Insert each QIAquick column into a luer connector on the Luer Adapter(s) in the manifold. Seal unused luer connectors with plugs provided with the QIAvac Luer Adapter Set. Other vacuum manifolds: follow the supplier's instructions. Insert each QIAquick column into a luer connector. 3. To bind DNA, load the samples into the QIAquick columns by decanting or pipetting, and apply vacuum. After the samples have passed through the column, switch off the vacuum source. The maximum loading volume of the column is 800 ul. For sample volumes greater than 800 ul simply load again. QIAquick Spin Handbook 07/2002 4. To wash, add 0.75 ml of Buffer PE to each QIAquick column and apply vacuum. 5. Transfer each QIAquick column to a microcentrifuge tube or the provided 2 ml collection tubes. Centrifuge for 1 min at 13,000 rpm (~ 17,900 x g). IMPORTANT: This spin is necessary to remove residual ethanol (Buffer PE). 6. Place each QIAquick column into a clean 1.5 ml microcentrifuge tube. 7. To elute DNA, add 50 ul of Buffer EB (10 mM Tris-Cl, pH 8.5) or H20 to the center of each QIAquick membrane, and centrifuge the columns for 1 min at 13,000 rpm (~17,900xg). Alternatively, for increased DNA concentration, add 30 ul elution buffer to the center of each QIAquick membrane, let the columns stand for 1 min, and then centrifuge. IMPORTANT: Ensure that the elution buffer is dispensed directly onto the QIAquick membrane for complete elution of bound DNA. The average eluate volume is 48 ul from 50 ul elution buffer volume, and 28 ul from 30 ul elution buffer. Elution efficiency is dependent on pH. The maximum elution efficiency is achieved between pH 7.0 and 8.5. When using water, make sure that the pH value is within this range, and store DNA at -20°C as DNA may degrade in the absence of a buffering agent. The purified DNA can also be eluted in TE (10 mM Tris-Cl, 1 mM EDTA, pH 8.0), but the EDTA may inhibit subsequent enzymatic reactions. 20 QIAquick Spin Handbook 07/2002 QIAquick Nucleotide Removal Kit Protocol using a microcentrifuge This protocol is designed for cleanup of radioactive-, biotin-, or DIG-labeled DNA fragments and oligonucleotides >17 nucleotides from enzymatic reactions (see page 8). The protocol ensures removal of primers <10 bases, enzymes, salts, and unincorporated nucleotides. It is possible to use this kit with a vacuum manifold as well as with a microcentrifuge, and a protocol for vacuum processing is available on request from QIAGEN Technical Services or your local distributor. However, we do not recommend processing radioactive samples with a vacuum manifold. Notes: • Add ethanol (96-1 00%) to Buffer PE before use (see bottle label for volume). • All centrifugation steps are in a conventional tabletop microcentrifuge. 1. Add 10 volumes of Buffer PN to 1 volume of the reaction sample and mix. For example, add 500 ul Buffer PN to a 50 ul reaction sample. For DNA fragments >1 00 bp, only 5 volumes of Buffer PN are required. 2. Place a QIAquick spin column in a provided 2 ml collection tube. 3. To bind DNA, apply the sample to the QIAquick column and centrifuge for 1 min at 6000 rpm. 4. For radioactive samples: Place the QIAquick column into a clean 2 ml collection tube and discard the tube containing the radioactive flow-through appropriately. For non-radioactive samples: Discard the flow-through and place QIAquick column back into the same tube. Collection tubes are re-used to reduce plastic waste. 5. For radioactive samples: To wash QIAquick column, add 500 ul of Buffer PE and centrifuge for 1 min at 6000 rpm. Discard the flow-through appropriately and repeat wash with another 500 ul of Buffer PE. For non-radioactive samples: To wash QIAquick column, add 750 ul of Buffer PE and centrifuge for 1 min at 6000 rpm. 6. Discard the flow-through and place the QIAquick column back in the same tube, which should be empty. Centrifuge for an additional 1 min at 13,000 rpm (~ 17,900 x a). IMPORTANT: Residual ethanol from Buffer PE will not be completely removed unless the flow-through is discarded before this additional centrifuge. 7. Place the QIAquick column in a clean 1.5 ml microcentrifuge tube. QIAquick Spin Handbook 07/2002 21 8. To elute DNA, add 100-200 ul of Buffer EB (10 mM Tris-Cl, pH 8.5) or H20 to the center of the QIAquick membrane and centrifuge the column for 1 min at 13,000 rpm (~17,900 x g). Alternatively, for increased DNA concentration, add 30-50 ul elution buffer to the center of the QIAquick membrane, let the column stand for 1 min, and then centrifuge. IMPORTANT: Ensure that the elution buffer is dispensed directly onto the QIAquick membrane for complete elution of bound DNA. Elution efficiency is dependent on pH. The maximum elution efficiency is achieved between pH 7.0 and 8.5. When using water, make sure that the pH value is within this range, and store DNA at -20°C as DNA may degrade in the absence of a buffering agent. The purified DNA can also be eluted in TE (10 mM Tris-Cl, 1 mM EDTA, pH 8.0), but the EDTA may inhibit subsequent enzymatic reactions. 22 QIAquick Spin Handbook 07/2002 QlAquick Gel Extraction Kit Protocol using a microcentrifuge This protocol is designed to extract and purify DNA of 70 bp to 10 kb from standard or low-melt agarose gels in TAE or TBE buffer. Up to 400 mg agarose can be processed per spin column. This kit can also be used for DNA cleanup from enzymatic reactions (see page 8). For DNA cleanup from enzymatic reactions using this protocol, add 3 volumes of Buffer QG and 1 volume of isopropanol to the reaction, mix, and proceed with step 6 of the protocol. Alternatively, use the new MinElute Reaction Cleanup Kit. Notes: • The yellow color of Buffer QG indicates a pH <7.5. • Add ethanol (96-1 00%) to Buffer PE before use (see bottle label for volume). • Isopropanol (100%) and a heating block or water bath at50°C are required. • All centrifugation steps are carried out at 13,000 rpm (~1 7,900 x g) in a conventional table-top microcentrifuge. • 3 M sodium acetate, pH 5.0, may be necessary. 1. Excise the DNA fragment from the agarose gel with a clean, sharp scalpel. Minimize the size of the gel slice by removing extra agarose. 2. Weigh the gel slice in a colorless tube. Add 3 volumes of Buffer QG to 1 volume of gel (100 mg~ 100 ul). For example, add 300 ul of Buffer QG to each 100 mg of gel. For >2% agarose gels, add 6 volumes of Buffer QG. The maximum amount of gel slice per QIAquick column is 400 mg; for gel slices >400 mg use more than one QIAquick column. 3. Incubate at 50°C for 10 min (or until the gel slice has completely dissolved). To help dissolve gel, mix by vortexing the tube every 2-3 min during the incubation. IMPORTANT: Solubilize agarose completely. For >2% gels, increase incubation time. 4. After the gel slice has dissolved completely, check that the color of the mixture is yellow (similar to Buffer QG without dissolved agarose). If the color of the mixture is orange or violet, add 10 ul of 3 M sodium acetate, pH 5.0, and mix. The color of the mixture will turn to yellow. The adsorption of DNA to the QIAquick membrane is efficient only at pH <7.5. Buffer QG contains a pH indicator which is yellow at pH <7.5 and orange or violet at higher pH, allowing easy determination of the optimal pH for DNA binding. 5. Add 1 gel volume of isopropanol to the sample and mix. For example, if the agarose gel slice is 1 00 mg, add 1 00 ul isopropanol. This step increases the yield of DNA fragments <500 bp and >4 kb. For DNA fragments between 500 bp and 4 kb, addition of isopropanol has no effect on yield. Do not centrifuge the sample at this stage. QIAquick Spin Handbook 07/2002 23 6. Place a QIAquick spin column in a provided 2 ml collection tube. 7. To bind DNA, apply the sample to the QIAquick column, and centrifuge for 1 min. The maximum volume of the column reservoir is 800 ul. For sample volumes of more than 800 ul, simply load and spin again. 8. Discard flow-through and place QIAquick column back in the same collection tube. Collection tubes are re-used to reduce plastic waste. 9. (Optional): Add 0.5 ml of Buffer QG to QIAquick column and centrifuge for 1 min. This step will remove all traces of agarose. It is only required when the DNA will subsequently be used for direct sequencing, in vitro transcription or microinjection. 10. To wash, add 0.75 ml of Buffer PE to QIAquick column and centrifuge for 1 min. Note: If the DNA will be used for salt sensitive applications, such as blunt-end ligation and direct sequencing, let the column stand 2-5 min after addition of Buffer PE, before centrifuging. 11. Discard the flow-through and centrifuge the QIAquick column for an additional 1 min at 13,000 rpm (~ 17,900 x g). IMPORTANT: Residual ethanol from Buffer PE will not be completely removed unless the flow-through is discarded before this additional centrifugation. 12. Place QIAquick column into a clean 1.5 ml microcentrifuge tube. 13. To elute DNA, add 50 ul of Buffer EB (10 mM Tris-Cl, pH 8.5) or H20 to the center of the QIAquick membrane and centrifuge the column for 1 min. Alternatively, for increased DNA concentration, add 30 ul elution buffer to the center of the QIAquick membrane, let the column stand for 1 min, and then centrifuge for 1 min. IMPORTANT: Ensure that the elution buffer is dispensed directly onto the QIAquick membrane for complete elution of bound DNA. The average eluate volume is 48 ul from 50 ul elution buffer volume, and 28 ul from 30 ul. Elution efficiency is dependent on pH. The maximum elution efficiency is achieved between pH 7.0 and 8.5. When using water, make sure that the pH value is within this range, and store DNA at -20°C as DNA may degrade in the absence of a buffering agent. The purified DNA can also be eluted in TE (1 0 mM Tris-Cl, 1 mM EDTA, pH 8.0), but the EDTA may inhibit subsequent enzymatic reactions. 24 QIAquick Spin Handbook 07/2002 QlAquick Gel Extraction Kit Protocol using a vacuum manifold QIAquick spin columns can now be used on any vacuum manifold with luer connectors, e.g., QIAvac 6S with Luer Adapters. The following protocol is designed to extract and purify DNA of 70 bp to 10 kb from standard or low-melt agarose gels in TAE or TBE buffer using vacuum-driven processing. Up to 400 mg agarose can be processed per spin column. This kit can also be used for DNA cleanup from enzymatic reactions (see page 8). For DNA cleanup from enzymatic reactions using this protocol, add 3 volumes of Buffer QG and 1 volume of isopropanol to the reaction and mix. Set up the vacuum manifold as described in step 3 and then and proceed with step 6 of the protocol. Alternatively, use the new MinElute Reaction Cleanup Kit. Notes: • The yellow color of Buffer QG indicates a pH <7.5. • Add ethanol (96-1 00%) to Buffer PE before use (see bottle label for volume). • Isopropanol (100%) and a heating block or water bath at50°C are required. • Switch off vacuum between steps to ensure that a consistent, even vacuum is applied during manipulations. • 3 M sodium acetate, pH 5.0, may be necessary. 1. Excise the DNA fragment from the agarose gel with a clean, sharp scalpel. Minimize the size of the gel slice by removing extra agarose. 2. Weigh the gel slice in a colorless tube. Add 3 volumes of Buffer QG to 1 volume of gel (100 mg~ 100 ul). For example, add 300 ul of Buffer QG to each 100 mg of gel. For >2% agarose gels, add 6 volumes of Buffer QG. The maximum amount of gel slice per QIAquick column is 400 mg; for gel slices >400 mg use more than one QIAquick column. 3. Incubate at 50°C for 10 min (or until the gel slice has completely dissolved). To help dissolve gel, mix by vortexing the tube every 2-3 min during the incubation. IMPORTANT: Solubilize agarose completely. For >2% gels, increase incubation time. During the incubation, prepare the vacuum manifold and QIAquick columns: QIAvac 24 (see page 30, and Figure 6): • Place the QIAvac 24 lid on top of the QIAvac 24 base. Make sure that the gasket fits tightly in the groove of the QIAvac 24 lid. • Insert up to 24 QIAquick spin columns into the luer extensions of the QIAvac 24. Close unused positions with luer caps and connect QIAvac 24 to a vacuum source. QIAquick Spin Handbook 07/2002 25 QIAvac 6S manifold (see page 30, and Figure 7): • Open QIAvac 6S lid. Place QIAvac Luer Adapter(s), or blanks to seal unused slots, into the slots of QIAvac top plate, and close the QIAvac 6S lid. Place the waste tray inside the QIAvac base, and place the top plate squarely over the base. Attach the QIAvac 6S to a vacuum source. • Insert each QIAquick column into a luer connector on the Luer Adapter(s) in the manifold. Seal unused luer connectors with plugs provided with the QIAvac Luer Adapter Set. Other vacuum manifolds: follow the suppliers instructions. Insert each QIAquick-column into a luer connector. 4. After the gel slice has dissolved completely, check that the color of mixture is yellow (similar to Buffer QG without dissolved agarose). If the color of the sample is orange or violet, add 1 0 ul of 3 M sodium acetate, pH 5.0, and mix. The color of the mixture will turn to yellow. The adsorption of DNA to the QIAquick membrane is efficient only at pH <7.5. Buffer QG contains a pH indicator which is yellow at pH <7.5 and orange or violet at higher pH, allowing easy determination of the optimal pH for DNA binding. 5. Add 1 gel volume of isopropanol to the sample and mix. For example, if the agarose gel slice is 1 00 mg, add 1 00 ul isopropanol. This step increases the yield of DNA fragments <500 bp and >4 kb. For DNA fragments between 500 bp and 4 kb, addition of isopropanol has no effect on yield. Do not centrifuge the sample at this stage. 6. To bind DNA, pipet the sample onto the QIAquick column and apply vacuum. After the sample has passed through the column, switch off vacuum source. The maximum volume of the column reservoir is 800 ul. For sample volumes of more than 800 ul, simply load again. 7. (Optional): Add 0.5 ml of Buffer QG to QIAquick column and apply vacuum. This step will remove all traces of agarose. It is only required when the DNA will subsequently be used for direct sequencing, in vitro transcription or microinjection. 8. To wash, add 0.75 ml of Buffer PE to QIAquick column and apply vacuum. Note: If the DNA will be used for salt sensitive applications, such as blunt-end ligation and direct sequencing, let the column stand 2-5 min after addition of Buffer PE before applying vacuum. 26 QIAquick Spin Handbook 07/2002 9. Transfer QIAquick column to a clean 1.5 ml microcentrifuge tube or to a provided 2 ml collection tube. Centrifuge for 1 min at 13,000 rpm (~ 17,900 x g). IMPORTANT: This spin is necessary to remove residual ethanol (Buffer PE). 10. Place QIAquick column in a clean 1.5 ml microcentrifuge tube. 11. To elute DNA, add 50 ul of Buffer EB (10 mM Tris-Cl, pH 8.5) or H20 to the center of the QIAquick membrane and centrifuge the column for 1 min at 13,000 rpm (~ 17,900 x g). Alternatively, for increased DNA concentration, add 30 ul elution buffer, let stand for 1 min, and then centrifuge for 1 min. IMPORTANT: Ensure that the elution buffer is dispensed directly onto the QIAquick membrane for complete elution of bound DNA. The average eluate volume is 48 ul from 50 ul elution buffer volume, and 28 ul from 30 ul. Elution efficiency is dependent on pH. The maximum elution efficiency is achieved between pH 7.0 and 8.5. When using water, make sure that the pH value is within this range, and store DNA at -20°C as DNA may degrade in the absence of a buffering agent. The purified DNA can also be eluted in TE (1 0 mM Tris-Cl, 1 mM EDTA, pH 8.0), but the EDTA may inhibit subsequent enzymatic reactions. QIAquick Spin Handbook 07/2002 27 Troubleshooting Guide This troubleshooting guide may be helpful in solving any problems which may arise. The scientists at QIAGEN Technical Services are always happy to answer any questions you may have about either the information and protocol(s) in this handbook or molecular biology applications (see inside front cover). Comments and Suggestions Low or no recovery • Buffer PE did not contain ethanol • Inappropriate elution buffer • Elution buffer incorrectly dispensed Gel • Gel slice incompletely solubilized Gel • pH of electrophoresis buffer too high (binding mixture turns orange or violet] Gel • Gel slice was too large (>400 mg] Gel • Cloudy and gelatinous appearance of sample mixture after addition of isopropanol Ethanol must be added to Buffer PE (concentrate) before use. Repeat procedure with correctly prepared Buffer PE. DNA will only be eluted efficiently in the presence of low-salt buffer (e.g., Buffer EB: 1 0 mM Tris-Cl, pH 8.5) or water. See "Elution in low-salt solutions", page 13. Add elution buffer to the center of the QIAquick membrane to ensure that the buffer completely covers the membrane. This is particularly important when using small elution volumes (30 ul). After addition of Buffer QG to the gel slice, mix by vortexing the tube every 2-3 minutes during the 50°C incubation. DNA will remain in any undissolved agarose. The electrophoresis buffer has been repeatedly used or incorrectly prepared, resulting in a sample pH that exceeds the buffering capacity of Buffer QG and leads to inefficient DNA binding. Add 1 0 ul of 3 M sodium acetate, pH 5.0, to the sample and mix. The color of the mixture will turn yellow indicating the correct pH for DNA binding. Even for binding mixtures with only small color changes (slight orange color), add the 1 0 ul sodium acetate. 70-80% recovery can only be obtained from <400 mg gel slice per QIAquick column. For gel slices >400 mg, use multiple QIAquick columns. This may be due to salt precipitation, and will disappear upon mixing the sample. Alternatively, the gel slice may not be completely solubilized. In this case, apply the mixture to the QIAquick column, centrifuge, and then add 0.5 ml Buffer QG to the column. Let stand for 1 min at room temperature, and then centrifuge and continue with the procedure. This additional wash will solubilize remaining agarose. 28 QIAquick Spin Handbook 07/2002 Comments and Suggestions DNA does not perform well, • Salt concentration in eluate too high • Eluate contains residual ethanol Gel • Eluate contaminated with agarose PCR • Eluate contains primer-dimers • Eluate contains denatured ssDNA, which appears as smaller smeared band on an analytical gel e.g., in ligation reactions Modify the wash step by incubating the column for 5 min at room temperature after adding 750 ul of Buffer PE, then centrifuge. Ensure that the wash flow-through is drained from the collection tube and that the QIAquick column is then centrifuged at 1 3,000 rpm (~1 7,900 x g) for an additional 1 min. The gel slice is incompletely solubilized or weighs >400 mg. Repeat procedure, including the optional Buffer QG column-wash step. Primer-dimers formed are longer than 20 bp, and are not completely removed. After the binding step, wash the QIAquick column with 750 ul of a 35% guanidine hydrochloride aqueous solution (35 gin 100 ml). Continue with the Buffer PE wash step and the elution step as in the protocol. Use the eluted DNA to prepare the subsequent enzymatic reaction but omit the enzyme. To reanneal the ssDNA, incubate the reaction mixture at 95°C for 2 min, and allow the tube to cool slowly to room temperature. Add the enzyme and proceed as usual. Alternatively, the DNA can be eluted in 10 mM Tris buffer containing 10 mM NaCI. The salt and buffering agent promote the renaturation of DNA strands. However the salt concentration of the eluate must then be considered for subsequent applications.

The following recommendations should be followed when handling the QIAvac 6S vacuum manifold. • Always store QIAvac 6S vacuum manifold clean and dry. To clean, simply rinse all components with water and dry with paper towels. Do not air-dry, as the screws may rust and need to be replaced. Do not use abrasives or solvents. • Always place the QIAvac 6S vacuum manifold on a secure bench top or work area. If dropped, the manifold may crack. • The components of QIAvac manifolds are not resistant to ethanol, methanol, or other organic solvents (Table 4). Do not bring solvents into contact with the vacuum manifold. If solvents are spilled on the unit, rinse thoroughly with distilled water, and do not incubate acrylic components in alcohol-containing reagents for long periods of time. Ensure that no residual Buffer PE remains in the vacuum manifold. • To ensure consistent performance, do not apply silicone or vacuum grease to any part of the QIAvac 6S manifold. The spring lock on the top plate and the self-sealing gasket provide an airtight seal when vacuum is applied to the assembled unit. To maximize gasket lifetime, rinse the gasket free of salts and buffers after each use and dry with paper towels before storage. • Remove blanks from the slots of the top plate after use and store them under the manifold.
