Abstract: |
A mineralized genetically recombinant collagen composition for repairing bone is prepared through preparing the solution of genetically recombinant collagen in acid or water, dropping Ca ions contained solution in it while stirring, adding PO4 ions contained solution, regulating pH value, stirring, laying aside, centrifugal separation and washing several times, and freeze drying. It has high biocompatibility. |
