英文摘要reactive continuous rods of macroporous poly(glycidyl methacrylate-co-ethylene dimethacrylate) were prepared within the confines of a stainless steel column. then papain was immobilized on these monoliths either directly or linked by a spacer arm. in a further step, a protein a affinity column was used for the characterization of the digestion products of human immunoglobulin g (igg) by papain. the results showed that papain immobilized on the monolithic rod through a spacer arm exhibits higher activity for the digestion of human igg than that without a spacer arm. the apparent michaelis-menten kinetic constants of free and immobilized papain, k-m and v-max, were determined. the digestion conditions of human igg with free and immobilized papain were optimized. comparison of the thermal stability of free and immobilized papain showed that the immobilized papain exhibited higher thermal stability than the free enzyme. the half-time of immobilized papain reaches about a week under optimum ph and temperature conditions.
