Abstract

V originále

Evaluating the physiological state of an organism is of clinical importance. In assisted reproduction, knowledge of the embryo’s physiology is crucial for selecting the embryo with the highest developmental capacity to ensure high pregnancy rates. Amino acids (AAs) are involved in many biochemical processes during embryo development, which means that the determination of AA fluctuations in the embryo’s surroundings can determine the embryo’s physiological state. Since current embryo selection methods are mainly based on visual assessment, which lacks proper accuracy, a novel method for the analysis of AAs in the embryo’s surroundings was developed. AAs were analyzed by means of MEKC-LIF after on capillary derivatization by naphthalene 2,3 dicarboxaldehyde. The reactants were injected under the three zone arrangement and mixed using the transverse diffusion of laminar flow profiles methodology. The resulting derivatives of all the standard AAs were baseline resolved in the background electrolyte comprised of 35 mM sodium tetraborate, 55 mM SDS, 2.7 M urea, 1 mM BIS-TRIS propane, and 23 mM NaOH within 50 minutes. The method was applied on an analysis of spent commercially available culture media used in assisted reproduction to culture embryos after in vitro fertilization.

In Czech

Význam asistované reprodukce roste vzhledem k rostoucímu počtu párů trpících neplodností. Klíčovými kroky asistované reprodukce jsou in vitro oplodnění vajíčka, kultivace embrya a výběr embrya s nejvyšším vývojovým potenciálem pro implantaci do dělohy. Současné stanovování vývojového potenciálu embrya je nepřesné, a proto jsou vyhledávány nové techniky k jeho lepšímu stanovení. Bylo vyvinutu MEKC-LIF stanovení aminokyselin po on-capillary derivatizaci pomocí TDLFP. Vyvinutá metoda byla úspěšně využita k analýze několika vzorků kultivačních médií odebraných po kultivaci embrya.
