Recombinant Human Bone Morphogenetic Protein-2 (rhBMP-2) with Additional Protein Domain Synthesized in E. coli : In Vivo Osteoinductivity in Experimental Models on Small and Large Laboratory Animals

Recombinant human bone morphogenetic protein-2 with an additional s-tag domain (s-tag-BMP-2) synthesized in E. coli is characterized by higher solubility and activity than the protein without additional s-tag domain, which increases the yield during purification and simplifies protein introduction into the osteoplastic materials. The high osteoinductivity of the demineralized bone matrix with s-tag-BMP-2 was shown on the model of regeneration of cranial defects of a critical size in mice and on the model of implantation of porous titanium matrix into defects of femoral and tibial bones in rabbits.
