英文摘要a novel thiol-ene "click" strategy for the preparation of monolithic trypsin microreactor was proposed. the hybrid organic-inorganic monolithic capillary column with ene-functionality was fabricated by sol-gel process using tetramethoxysilane (tmos) and gamma-methacryloxypropyltrimethoxysilane (gamma-maps) as precursors. the disulfide bonds of trypsin were reduced to form free thiol groups. then the trypsin containing free thiol groups was attached on the gamma-maps hybrid monolithic column with ene-functionality via thiol-ene click chemistry to form a trypsin microreactor. the activity of the trypsin microreactor was characterized by detecting the substrate (n alpha-p-tosyl-l-arginine methyl ester hydrochloride. tame) and the product (n alpha-p-tosyl-l-arginine, ta) with on-line capillary zone electrophoresis. after investigating various synthesizing conditions, it was found that the microreactor with poly(n,n'-methylenebisacrylamide) as spacer can deliver the highest activity, yielding a rapid reaction rate. after repeatedly sampling and analyzing for 100 times, the monolithic trypsin microreactor still remained 87.5% of its initial activity. it was demonstrated that thiol-ene "click" strategy for the construction of enzyme microreactor is a promising method for the highly selective immobilization of proteins under mild conditions, especially enzymes with free thiol radicals.
