Recombinant Human BMP‑7 (Catalog # 354-BP) under non-reducing conditions only
Measured by its ability to neutralize BMP‑7-induced alkaline phosphatase production in the ATDC5 mouse chondrogenic cell line. Erlacher, L. et al. (1998) J. Bone Miner. Res. 13:383. The Neutralization Dose (ND50) is typically 1.5-6.0 µg/mL in the presence of 1 µg/mL Recombinant Human BMP‑7 and 50 µg/mL L-ascorbic acid.
Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.
Alkaline Phosphatase Production Induced by BMP‑7 and Neutralization by Human BMP‑7 Antibody.
Recombinant Human BMP‑7 (Catalog # 354‑BP) induces alkaline phosphatase production in the the ATDC5 mouse chondrogenic cell line in a dose-dependent manner (orange line). Alkaline phosphatase production elicited by Recombinant Human BMP‑7 (1 µg/mL) is neutralized (green line) by increasing concentrations of Mouse Anti-Human BMP‑7 Monoclonal Antibody (Catalog # MAB3541). The ND50 is typically 1.5-6.0 µg/mL in the presence of L-ascorbic acid (50 µg/mL).
BMP‑7 was detected in immersion fixed paraffin-embedded sections of human kidney using Mouse Anti-Human BMP‑7 Monoclonal Antibody (Catalog # MAB3541) at 15 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Mouse HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS002) and counterstained with hematoxylin (blue). Specific staining was localized to cytoplasm in convoluted tubules. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.

Bone morphogenetic protein 7 (BMP-7), also known as osteogenic protein 1 (OP-1), is a widely expressed TGF-beta superfamily member with important functions during embryogenesis, in the adult, and in disease (1, 2). Human BMP-7 is synthesized with a 29 amino acid (aa) signal sequence, a 263 aa propeptide, and a 139 aa growth factor domain (3, 4). The growth factor domain of human BMP-7 shares 98% aa sequence identity with mouse and rat BMP-7. The BMP-7 propeptide is cleaved intracellularly but often remains associated with the mature C-terminus. Based on in vivo and in vitro studies, BMP-7 has the potential to be secreted as a disulfide‑linked mature homodimer, or particularly as a heteromeric complex that consists of two propeptides noncovalently associated with a mature disulfide‑linked homodimer (5, 6). The presence of the propeptides in BMP-7 appears to stabilize the molecule and provide a docking mechanism for extracellular storage on molecules such as fibrillin-1 and -2 (5, 6). The propeptides themselves do not impart latency to the complex. BMP-7 binding to type II receptors rapidly displaces the prodomain:mature molecule interaction and has no effect on activity. But it is suggested that immobilized BMP-7 (via prodomain:fibrillin) is inactive, allowing for possible long-term storage of the molecule (6). BMP-7 interacts with the type 2 receptors Activin RIIA, Activin RIIB, and BMPR-II and the type 1 receptors Activin RIA, BMPR-IA, and BMPR-IB (2, 6). BMP-7 may also be processed into a disulfide‑linked heterodimer with either BMP-2 or BMP-4. Such complexes may show increased potency and range of activity compared to BMP-7 homodimers (7‑9). BMP-7 plays a role in a variety of organ systems. It promotes new bone formation and nephron development (10, 11), inhibits the branching of prostate epithelium (12), and antagonizes epithelial-mesenchymal transition (EMT) (13‑15). In pathological conditions, BMP-7 inhibits tumor growth and metastasis (14), ameliorates fibrotic damage in nephritis (13), and promotes neuroregeneration following brain ischemia (16).
