Abstract
A method of producing a pharmaceutical preparation comprising fibronectin and fibrinogen is disclosed. The method involves admixing into a starting solution of fibrinogen and fibronectin, in a single step, a precipitating composition comprising a polyalkylene glycol and at least one of glycine and &bgr;-alanine which forms a precipitate. Next, the precipitate is collected and a pharmaceutical preparation is prepared from the precipitate. The pharmaceutical preparation has a fibronectin:fibrinogen ratio from about 0.02 to about 0.2.
