Recombinant human N-TERMINAL---Human BMP-2 (Met 1 – Arg 282) Human BMP-7 (Ser 293 – Arg 431)---C-TERMINAL. The DNA sequence encoding the human BMP-2 signal peptide and propeptide (1~282 amino acid) fused to the human rhBMP-7 mature chain (293~431 amino acid) was expressed in a Chinese hamster ovary cell line. The mature recombinant BMP-7 generated by the proteolytic removal of the signal peptide and propetide contains 139 amino acid residues. The glycosylation of BMP-7 increases the molecular mass and the glycosylated proteins migrate as 25 ~ 40 kDa in SDS-PAGE under non-reducing conditions. BMP-7 is purified by proprietary chromatographic techniques.
Synonyms: Osteogenic Protein 1, BMP-7.
Formulation: BMP-7 was lyophilized from a concentrated (1mg/ml) sterile solution containing 1% sucrose, 1.2% mannitol, 20 mM glycine and 0.05% polysorbate 20 pH 4.
Physical Appearance: Sterile Filtered White lyophilized (freeze-dried) powder.
Purity: Greater than 97% as determined by: (a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE.
Source: Chinese Hamster Ovarian Cells.
Uniprot ACC number: P18075
Transportation method: Shipped at room temperature.
Stability: Lyophilized BMP-7 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution BMP 7 Human should be stored at +4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.
Biological Activity: Measured in alkaline pH ospH atase activity assay using MC3T3-E1 cells. The ED50 for this effect is < 70 ng/ml, corresponding to a Specific Activity of 14, 286IU/mg.
Solubility: It is recommended to reconstitute the lyophilized Bone Morphogenetic Protein-7 in 0.5mg/1ml sterile/ endotoxin free water.
