毛細管電泳於生物分子辨識及組合化學之應用

Capillary Electrophoresis in Biomolecular Recognition and Combinatorial Chemistry

摘要


電泳是由於帶電物質在電場中受吸引或排斥而遷移所形成,毛細管電泳是依據不同物質在毛細管中受電場影響而具有不同的遷移速率來達到分離的效果,毛細管電泳相當適合於生命科學領域的研究,本文特別就毛細管電泳在生物分子辨識及組合化學分子間高效率篩選上的特殊應用作一整體性的描述。

Capillary electrophoresis is useful for the studies of biomolecular recognitions and the screening of libraries. Its applications reported in the literature include the separation of racemic biomolecules, the measurement of binding constants, the estimation of kinetic rate constants, the determination of stoichiometries, the examination of electrostatic interactions, the estimation of effective charges and molecular weights of proteins, the characterization of enzymatic activities, and library screening for drug candidates in solutions. This technique demands only small amounts of samples, involves no radiolabeled or fluorescently labeled materials and chemically immobilized ligands, and does not require changes in spectroscopic characteristics upon binding. This paper reviews the most recent applications of capillary electrophoresis and its use in the analysis of biomolecules.
