Description
Description
Bone morphogenetic protein 2 (BMP-2) is a member of the BMP subgroup, where BMP2-7 belongs to TGF- β Superfamily. It plays a dominant role in embryonic dorsal ventral pattern, organogenesis, limb bud formation, and bone formation and regeneration. Mature human BMP-2 exhibits 100% aa sequence identity with mouse and rat BMP-2. It has 85% sequence identity with human BMP-4 and less than 51% sequence identity with other BMPs. Normal bone formation is a carefully regulated long-term process that involves the continuous expression of growth regulatory factors by osteoblasts during proliferation and final differentiation. Due to the ordered sequence of gene expression in osteoblasts indicating cascading effects, BMP-2 can initiate and maintain this effect. BMP-2 also promotes the maintenance and repair of colonic epithelium, inhibits the synthesis and release of dopamine in neurons, induces apoptosis in medulloblastoma cells, and is essential for myocardial contractility.

Reconstitution |
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤ -20℃. Further dilutions should be made in appropriate buffered solutions. |
Shipping and Storage
