摘要

To avoid the risk of unwanted side reactions from blood products, especially from albumin and immunoglobulin G preparations, the latter are prepared from plasma using chymotrypsin to inactivate prekallikrein activator, these preparations being obtained by fractional concentration of plasma proteins, with the proviso that in any desired stage of the fractionation process a chymotrypsin solution or immobilised chymotrypsin is added to the fractions, and before the preparations are finished the chymotrypsin or the immobilised chymotrypsin is removed from the preparations.
