- TGF-beta family members are key modulators of cell proliferation, differentiation, matrix synthesis, and apoptosis. As implied by their name, BMPs initiate, promote, and regulate the development, growth and remodeling of bone and cartilage. In addition to this role, BMPs are also involved in prenatal development and postnatal growth, remodeling and maintenance of a variety of other tissues and organs. BMP-3 is abundantly found in adult bone, and to a lesser extent fetal cartilage. BMP-3 inhibits osteogenesis and bone formation by activating a signaling cascade that antagonizes the signaling of pro-osteogenic BMPs. Recombinant human BMP-3 is a disulfide linked homodimeric protein that corresponds to residues 361 to 472 of the 472 amino acid BMP-3 precursor protein.
- Product Overview
- Human BMP3 expressed in E.coli
- CAT# CSC-CTK0526-20 (20 μg); CAT# CSC-CTK0526-100 (100 μg)
- Greater than 95% as determined by HPLC and SDS-PAGE analysis.
- Determined by its ability to inhibit BMP-2-induced alkaline phosphatase production by ATDC-5 cells.
- Endotoxin Level
- Less than 1 EU/μg.
- Sterile-filtered through a 0.2 micron filter and lyophilized with no additives.
- Please centrifuge product briefly before opening vial. The lyophilized protein should be reconstituted in sterile, ultra-pure water to a concentration of 0.1 - 1.0 mg/ml. This solution can then be diluted into other aqueous buffers and stored at -20°C for future use.
- Storage & Stability
- The lyophilized protein, though stable at room temperature for up to 3 weeks, is best stored desiccated at -20°C. Reconstituted protein should be used immediately or stored long-term in undiluted working aliquots at -20°C. For long-term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Avoid repeated freeze-thaw cycles.
