TY - JOUR ID - 877280 AU - Musilová, Jindra - Glatz, Zdeněk PY - 2010 TI - Optimization of capillary electrophoretic method for determination of physiologically relevant nucleotides and coenzymes in cell extract PB - Univerzita Palackého, Olomouc, Česká rep CY - Univerzita Palackého, Olomouc, Česká rep SN - 9788024424705 KW - Nukleotid-Koenzym-Buněčný extrakt N2 - Due to importance of nucleotides and coenzymes for metabolism, the main aim of this work was to optimize capillary electrophoretic method for the selective and rapid determination of 17 energetically important metabolites (purine and pyrimidine nucleotides, adenine coenzymes and Acetyl CoA). For improvement of concentration sensitivity, the capillary zone electrophoresis (CZE) was combined with the on-line preconcentration technique -field enhanced sample stacking. The optimal separation was reached by using voltage 23 kV (positive polarity)and direct detection at 260, 280 and 340 nm. 50 mM concentration of phosphate buffer (pH 5.8) provided the best resolution of peaks. Resulting method showed RSD in the range from 0.65 to 1.40 % for migration time and from 2.37 to 5.99 % for relative peak area of metabolites (n=10). Optimized method was used for analyzing of cell-extract of bacterium Paracoccus denitrificans. ER -
