The affinity chromatography experiment was performed on a capillary electrophoresis instrument by using its pressure system as the driving force. Reactive monolithic capillary columns have been prepared by in-situ copolymerization of the monomers in the presence of porogenic dilute, and protein A was immobilized on the monolithic rods directly or through a 11 carbon atom space arm with molded synthetic methods. The non-specific adsorption of two kinds of media has been studied and the results showed that the medium without space arm gives very low non-specific adsorption of BSA. The affinity column without space arm was used to determine the human immunoglobulin G(HIgG) in human serum. The correlative coefficient of the calibration curve reaches 0 998 7. The total time of rapid analysis was less than 0 7 min. The consumption of eluent buffer and sample is much low than by conventional HPLC.展开更多
