Method of preparing collagenous tissue

摘要

A process of preparation of a collagenous prosthesis for removing cell membrane proteins from a biological collagenous tissue and preserving elasticity of the collagenous prosthesis comprises the following steps: (a) soaking the tissue in an organic detergent for a sufficient time to disrupt the cell membrane and to solubilize the cellular membrane proteins of the collagenous tissue; (b) extracting and removing the cellular membrane proteins from the collagenous tissue by mechanical washing to obtain the collagenous prosthesis; (c) preserving the collagenous prosthesis in alcohol.
