Bone morphogenetic protein 8B is a protein that in humans is encoded by the BMP8B gene. The protein encoded by this gene is a member of the TGF-β superfamily. It has close sequence homology to BMP7 and BMP5 and is believed to play a role in bone and cartilage development. BMP-8b, in contrast, is required for both the initiation and maintenance of spermatogenesis.

Source:
Escherichia coli

Endotoxin Test:
<0.01 EU per 1 μg of the protein by the LAL method. Activity:
Measure by its ability to induce alkaline phosphatase production by ATDC5 cells. The ED₅₀ for this effect is <21.8 ng/mL. Purity:
>98% as determined by SDS-PAGE. Ni-NTA chromatography

Formulation:
The protein was lyophilized from a solution containing 20 mM sodium citrate, 0.2 M NaCl, pH 3.5.

Reconstitution:
It is recommended to reconstitute the lyophilized protein in sterile H₂O to a concentration not less than 100 μg/mL and incubate the stock solution for at least 20 min to ensure sufficient re-dissolved.

Storage:
Lyophilized protein should be stored at -20°C. Upon reconstitution, protein aliquots should be stored at -20°C or -80°C.

Note:
Please use within one month after protein reconstitution.
