✦ Synopsis

Aminopropyl

silica gel was prepared from porous silica gel by reaction with yaminopropyltrimethoxysilane in toluene and was used for immobilizing chymotrypsin (EC 3.4.4.5) and human serum albumin. Immobilized chymotrypsin was used for the resolution of N-acetyl-Dt--phenylalanine and immobilized human serum albumin was used for the purification of goat anti-human serum albumin. Epoxy silica gel. prepared by reaction of porous silica gel with y-glycidoxypropyltriethoxysilane, was coupled with rtl-aminobenzamidine and the resulting matrix was used for trypsin purification.
