Measured in alkaline phosphatase activity assay using MC3T3-E1 cells. The ED50 for this effect is <100ng/ml corresponding to a Specific Activity of 10,000IU/mg.
BMP-7 was lyophilized from a concentrated (1mg/ml) sterile solution containing 1% sucrose, 1.2% mannitol, 20mM glycine, and 0.05% tween 20 pH-4.
Greater than 97.0% as determined by:
(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.
It is recommended to reconstitute the lyophilized Bone Morphogenetic Protein-7 in 1ml sterile/ endotoxin free water.
Chinese Hamster Ovarian Cells (CHO cell).
Lyophilized BMP-7 although stable at room temperature for 3 weeks, should be stored desiccated below -18oC. Upon reconstitution BMP 7 Human should be stored at 4oC between 2-7 days and for future use below -18oC.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.
Osteogenic Protein 1, BMP-7.
