Process for the industrial preparation of collagenous materials from human placental tissues; human collagenous materials obtained and their use in biomaterials

摘要

the preparation process consists of subjecting the placental tissue after pressing.grinding and washing in neutral and acid treatment in alkaline solution at a temperature of less than or equal to 10 c and then to the portions of the collagen solubilized in this respectly.and the solutions of collagen from a potential future treatment for at least partial solubilization of insoluble residue in a chromatographic purification resin exchangeuse of anion, at a temperature of less than or equal to 13 degrees, followed by fractional precipitation of collagen with acid salt.;human collagen materials obtained may be used as biomaterials, biotechnology and pharmaceutical safety of perfect human antibody.
