Selective Removal of Chymotrypsin Using Diphenyl α-Aminoalkylphosphonate Immobilized on Sepharose Gel

Abstract

A diphenyl α-aminoalkylphosphonate derivative, which is an irreversible inhibitor of chymotrypsin-like serine proteases, was immobilized on cyanogen bromide-activated Sepharose, and the selective binding of chymotrypsin to the obtained inhibitor-gel was evaluated using batch and column methods. Complete removal of chymotrypsin in an aqueous solution was done using the column method, while partial removal was done using the batch method.
