A METHOD FOR PRODUCING A PREPARATION BASED ON FIBRINOGEN AND FIBRONECTIN AS WELL AS PROTEIN COMPOSITIONS OBTAINABLE ACCORDING TO THIS METHOD

摘要

A method for producing protein compositions comprising fibrinogen andfibronectin is disclosed, wherein a fibrinogen and fibronectin-containingstarting solution is treated with a precipitating composition which comprisestwo different components that modify the solubility of fibrinogen and/orfibronectin, so that in a single-step precipitation a precipate is formedwhich comprises fibrinogen and fibronectin, and the precipitate formedoptionally is further treated by methods known per se.
