Process for the preparation of mature polypeptides by enzymatic cleavage with factor XA

摘要

The present invention relates to the preparation of mature polypeptides by the enzymatic hydrolysis of soluble precursors therefor with Factor Xa immobilized on an insoluble solid support. The use of the immobilised enzyme simplifies the process of producing the mature product, minimizes the probabilty of the final product being contaminated by the enzyme or by autolysis products or by other proteins of animal origin and enables the repeated use of the same support and better control of the hydrolysis of the precursor.
