Ac-Globulin (Factor V): Preparation of a Practical Product

Abstract
A procedure for the preparation of large quantities of very potent, high yield, partially pure bovine Ac-globulin concentrate, free of other clotting factors, is described. The isolation procedure involves a plasma recalcification step followed by ion exchange chromatography on a fully quaternized, amino ethyl cellulose. The resulting practical product is stable and represents virtually 100% yield with a purification of over 2000 times from bovine adsorbed plasma.
