Recombinant Human BMP-7 is a homodimeric glycoprotein consisting of two 117 amino acid subunits, which correspond to amino acid residues 315 to 431 of the full-length BMP-7 precursor. Recombinant Human BMP-7 has a calculated molecular weight of 26.4 kDa; however, due to glycosylation, the BMP-7 homodimer migrates at an apparent molecular weight
