Scientific Data

Bioactivity Recombinant Human BMP-2 GMP Protein BioactivityView Larger

GMP-grade Recombinant Human BMP-2 (Catalog # 355-GMP) induces alkaline phosphatase production in the ATDC5 mouse chondrogenic cell line. The ED50 for this effect is 40-200 ng/mL. Three independent lots were tested for activity and plotted on the same graph to show lot-to-lot consistency of GMP BMP-2.

SDS-PAGE Recombinant Human BMP-2 GMP Protein SDS-PAGEView Larger

1 μg/lane of GMP-grade Recombinant Human BMP-2 (Catalog # 355-GMP) was resolved with SDS-PAGE under reducing (R) and non-reducing (NR) conditions and visualized by silver staining, showing single bands at 15 kDa and 30 kDa, respectively.

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.

背景

Background: BMP-2

Bone morphogenetic protein 2 (BMP-2) is a member of the BMP subgroup of the TGF-beta superfamily. It plays a dominant role in embryonic dorsal-ventral patterning, organogenesis, limb bud formation, and bone formation and regeneration (1, 2). Human BMP‑2 is synthesized as a 396 amino acid (aa) preproprotein that contains a 23 aa signal sequence, a 259 aa prosegment, and a 114 aa mature region (3). Proteolytic removal of the propeptide enables mature BMP-2 to form active disulfide linked homodimers and heterodimers with BMP-7 (2). Mature monomeric BMP-2 is an 18 kDa glycosylated peptide with seven conserved cysteines that form a cystine knot structure (4). Mature human BMP-2 shares 100% aa sequence identity with mouse and rat BMP-2. It shares 85% aa sequence identity with human BMP-4 and less than 51% with other BMPs. BMP-2 signals through heterodimeric complexes composed of a type I receptor (Activin RI, BMPR‑IA, or BMPR‑IB) and a type II receptor (BMP RII or Activin RIIB) (2, 5). BMP-2 induces chondrocyte proliferation, endochondral bone formation, longitudinal bone growth, and bone and cartilage repair (6, 7). It induces ectopic bone formation or calcification by promoting osteogenic and chondrogenic differentiation in mesenchymal cells, stem cells, and vascular smooth muscle cells (2, 8‑10). BMP-2/BMP-7 heterodimers are significantly more potent than BMP-2 homodimers at inducing bone formation in vivo (11). BMP-2 also promotes the maintenance and repair of colonic epithelium, suppresses neuronal dopamine synthesis and release, induces apoptosis in medulloblastoma cells, and is required for cardiac contractility (12‑15).
