Title CHEMICALLY MODIFIED WATER-SOLUBLE ELASTIN, MIXED GELS OF CHEMICALLY MODIFIED WATER-SOLUBLE ELASTIN WITH COLLAGEN AND METHOD FOR PRODUCING SAME achieved
Abstract Disclosed is a medical material such as an artificial blood vessel, which is highly biocompatible and has sufficiently high elasticity, high extensibility and high strength, using water-soluble elastin and collagen. Specifically disclosed are: a chemically modified water-soluble elastin/collagen mixed gel obtained by mixing a chemically modified water-soluble elastin with almost the same weight of collagen, said chemically modified water-soluble elastin being obtained by partially or totally N-acylating a primary amine and a secondary amine contained in high-molecular water-soluble elastin molecules and partially or totally coupling carboxyl groups contained in said molecules with amino groups of an alkyl ester of an amino acid; a chemically modified water-soluble elastin/collagen mixed gel obtained by mixing a chemically modified water-soluble elastin with collagen, said chemically modified water-soluble elastin being used in an increased or decreased amount relative to the amount of collagen; and a chemically modified water-soluble elastin/collagen mixed gel obtained by irradiating the aforesaid mixed gel with radiation.
