Recombinant bone morphogenetic protein-2 is one of the members of the family of transforming growth factor beta super, has induced between undifferentiated mesenchymal stem cells into chondrocytes and osteoblasts directional differentiation and proliferation, and promote the osteoblast differentiation of mature, participated in the reconstruction of bone and cartilage growth and its process, thus accelerating bone defect repair. BMP - 2 body form before synthesis in the body, the proteases cut to remove signal peptide and the peptide,Mature peptide composed of 114 amino acid residues was obtained. The conserved structure of mature peptide was correctly folded by 7 pairs of disulfide bonds .

Purity	Greater than 95.0% as determined by SDS-PAGE .
