ABSTRACT:
In order to avoid the risk of undesired side reactions of blood products, the latter are produced from plasma by using chymotrypsin to inactivate prekallikrein activator. These preparations are obtained by the fractionated enrichment of plasma proteins, with the proviso that a chymotrypsin solution or immobilized chymotrypsin is added to the fractions at any stage of the fractionation process. Before completion of the preparations, the chymotrypsin or the immobilized trypsin is removed from the preparations.
