| titleOfInvention |
Composite collagen sponge and preparation method thereof |
| abstract |
The present invention discloses a kind of composite collagen sponge and a method for producing the same. The composite collagen sponge contains collagen, a cell growth factor and a protective agent, and the absorption amount thereof is 52 times or more. In the production method, purification step of the cation chromatograph and step of inactivation of the organic solvent / decontamination agent virus inactivation and dry heat virus inactivation are performed . The collagen sponge obtained by the method of the present invention not only enhanced the safety factor and performance in the clinical application of the product, but also ensured the stability of the product and the biological activity within the validity period. |
