Synonyms
BMP7, BMP-7, bone morphogenetic protein 7, Eptotermin alfa, OP-1,
Description
BMP-7 is a member of the TGF-β superfamily which is supposed to be one of the most potent anabolic factors of chondrocytes. The growth factor domain of human BMP-7 shares 98% aa sequence identity with mouse and rat BMP-7.
Molecular Weight
The protein has a predicted 13.1 kDa.
Purity
> 95% as determined by SDS-PAGE.
Biological Activity
Determined by its ability to induce alkaline phosphatase production by ATDC-5 cells.
The expected ED50 for this effect is 20-40 ng/ml.
Endotoxin
< 1 0EU /mg of the protein by the LAL method.
Formulation
Lyophilized from a 0.22 μm filtered solution containing 0.085% TFA, 30% ACN,5% mannitol.
Reconstitution
Centrifuge the tube before opening. It is recommended to redissolve in 4 mM HCl.
