| 反应种属 | Human/Mouse |
| 应用 | Western Blot(0.1 µg/mL) |
| 目标/特异性 | Detects human BMP-9 in direct ELISAs and Western blots. In direct ELISAs, 100% cross-reactivity with recombinant mouse BMP‑9 is observed. In direct ELISAs and Western blots, less than 2% cross-reactivity with recombinant human (rh) BMP-2, -3, -4, -5, -7, -8, and rhBMP‑10 is observed. |
| 使用方法 | Western Blot: 0.1 µg/mL Neutralization: Measured by its ability to neutralize BMP‑9-induced alkaline phosphatase production in the ATDC5 mouse chondrogenic cell line. The Neutralization Dose (ND50) is typically 0.08-0.3 µg/mL in the presence of 2 ng/mL Recombinant Human BMP‑9. |

| 背景 | Human BMP-9, also known as growth and differentiation factor 2 (GDF-2), is a member of the BMP subgroup of the TGF-beta superfamily proteins that signal through heterodimeric complexes composed of type I and type II BMP receptors. BMP-9 regulates the development and function of a variety of embryonal and adult tissues (1, 2). The human BMP-9 cDNA encodes a 429 amino acid (aa) precursor that includes a 22 aa signal sequence, a 298 aa propeptide, and a 111 aa mature protein (3). Unlike with other BMP family proteins, the propeptide does not interfere with the biological activity of BMP-9 and remains associated with the mature peptide after proteolytic cleavage (4). Human and mouse BMP-9 share 96% aa sequence identity. Within the mature protein, human BMP-9 shares 64% aa sequence identity with human BMP-10 and less than 50% aa sequence identity with other BMPs. BMP-9 is expressed by non-parenchymal cells in the liver, (5, 6) where it promotes lipid metabolism and inhibits glucose production (7). BMP-9 exerts a prolonged hypoglycemic effect which may be due to an enhancement of insulin release (7). BMP-9 interacts with a high affinity specific heteromeric receptor expressed on liver endothelial cells that has been identified as ALK-1 (4-6). In the embryonal CNS, BMP-9 functions in the development and maintenance of the cholinergic neuronal phenotype (8-10). BMP-9 also induces the differentiation of mesenchymal stem cells into the chondrogenic lineage (11, 12). At low concentrations, BMP-9 is a proliferative factor for hematopoietic progenitor cells, but at higher concentrations, it enhances TGF-beta 1 production and inhibits hematopoietic progenitor colony formation (13). |

Alkaline Phosphatase Production Induced by BMP‑9 and Neutralization by Human BMP‑9 Antibody. Recombinant Human BMP‑9 (Catalog # 3209‑BP) induces alkaline phosphatase production in the ATDC5 mouse chondrogenic cell line in a dose-dependent manner (orange line). Alkaline phosphatase production elicited by Recombinant Human BMP‑9 (2 ng/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Human BMP‑9 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3209). The ND50 is typically 0.08-0.3 µg/mL. |
