Product Specifications for Recombinant Human BMP-3 Protein, CF

Source	E. coli-derived human BMP-3 protein Gln363-Arg472, with an N-terminal Met
Purity	>95%, by SDS-PAGE under reducing conditions and visualized by silver stain
Endotoxin level	<0.10 EU per 1 μg of the protein by the LAL method.
N-terminal sequence Analysis	Met
Predicted Molecular Mass	12.5 kDa (monomer)
Activity	Measured by its ability to inhibit BMP-2-induced activity in MC3T3‑E1 mouse preosteoblast cells. Daluiski, A. et al. (2001) Nature Genetics 27:84. 30 µg/mL of hBMP-3 will antagonize hBMP-2 (0.25 µg/mL) induction of alkaline phosphatase in MC3T3E1 cells by >50%.

Formulation, Preparation and Storage

Carrier Free

What does CF mean?

CF stands for Carrier Free (CF). We typically add Bovine Serum Albumin (BSA) as a carrier protein to our recombinant proteins. Adding a carrier protein enhances protein stability, increases shelf-life, and allows the recombinant protein to be stored at a more dilute concentration. The carrier free version does not contain BSA.

What formulation is right for me?

In general, we advise purchasing the recombinant protein with BSA for use in cell or tissue culture, or as an ELISA standard. In contrast, the carrier free protein is recommended for applications, in which the presence of BSA could interfere.

Background: BMP-3

BMP-3, also known as osteogenin, the most abundant BMP in adult bone, is one of at least 15 structurally and functionally related BMPs, which are members of the TGF- beta superfamily (1 - 3). BMPs were originally identified as protein regulators of cartilage and bone formation. They have since been shown to be involved in embryogenesis and morphogenesis of various tissues and organs. BMPs also regulate the growth, differentiation, chemotaxis, and apoptosis of various cell types. Similar to most other TGF-beta family proteins, BMPs are highly conserved across animal species. At the amino acid sequence level, mature human and rat BMP-3 are 98% identical. BMP-3 is synthesized as a large precursor protein that is cleaved at the dibasic cleavage site (RXXR) to release the carboxy-terminal domain. Biologically active BMP-3 is a disulfide-linked homodimer of the carboxy-terminal 110 amino acid residues that contains the characteristic seven conserved cysteine residues involved in the formation of the cysteine knot and the single interchain disulfide bond (4). The role of BMP-3 in bone is contradictory since, unlike osteogenin purified from bone, recombinant BMP-3 has not shown osteogenic function (5). Several studies indicate that BMP-3 is an inhibitor of osteogenic BMPs. BMP-3 dorsalizes Xenopus embryos, the opposite effect of BMP-2 or 4, which cause ventralization. BMP-3 inhibits alkaline phosphatase production and induction of osteoblastic target genes in undifferentiated mesenchymal and osteogenic cell lines that have been treated with BMP-2. BMP-3 also induces the expression of TGF-beta /activin responsive genes, but not BMP-responsive genes. Since the inhibitory effect is not due to direct competition with osteogenic BMPs, it has been suggested that BMP-3 activates signaling through an activin pathway, resulting in antagonism of osteogenesis induced by other BMPs.
