Document Type and Number:
WIPO Patent Application WO2003020840
Kind Code:
A9
Abstract:
The present invention provides methods for purifying insoluble bone gelatin and uses for insoluble bone gelatin. The process for isolating insoluble bone gelatin from bone tissue includes grinding the bone tissue into bone powder; washing the bone powder with saline; demineralizing the bone tissue; contacting the bone powder with a neutral salt; and contacting the bone powder with a stabilizer. The present invention also discloses an insoluble bone gelatin including about 10 percent growth factor. Insoluble bone gelatin is useful, for example, in preparing impaction bone grafts.
