Method for producing vitronectin
First Claim
1. A method for recovering purified vitronectin from a biological material in which vitronectin is present, which consists essentially of contacting immobilized glycosaminoglycan with the biological material in the presence of a protein denaturing agent whereby the conformation of vitronectin present in the biological material is altered such that the binding activity of said vitronectin to glycosaminoglycan is selectivity increased whereby vitronectin binds selectively to the immobilized glycosaminoglycan and recovering the bound vitronectin.

Abstract
This invention deals with a simple and efficient method for producing vitronectin from biological materials which include vitronectin. More specifically, this invention deals with a method for producing vitronectin by binding vitronectin in biological materials to immobilized glycosaminoglycans in the presence of protein denaturing agent, especially urea.
