Method for the purification of collagens

摘要

Collagen affinity matrices are prepared, useful for separating collagenous substances from other high molecular weight proteinaceous substances. Fibronectin is fragmentated chemically or by enzymatic digestion, etc. Fragments of fibronectin, which retain the collagen-binding site but are severed from other binding sites of intact fibronectin, are selected and coupled to solid support material.
