BMP-3 蛋白, Human

BMP-3 Protein, a TGF-beta superfamily member, crucially influences early skeletal formation and acts as a bone density negative regulator. It counteracts osteogenic BMPs, hindering osteoprogenitor differentiation. BMP-3 initiates signaling via ACVR2B, activating SMAD2-dependent and SMAD-independent pathways, including TAK1 and JNK. Structurally, it forms homodimers with disulfide bonds, interacting with ACVR2B to regulate functions. BMP-3 Protein, Human is the recombinant human-derived BMP-3 protein, expressed by E. coli , with tag free. The total length of BMP-3 Protein, Human is 110 a.a., with molecular weight of ~12 kDa.

BMP-3 蛋白是 TGF-β 超家族的成员，在发育过程中发挥着至关重要的作用，特别是在诱导和形成早期骨骼形成方面，同时充当骨密度的负调节剂。值得注意的是，它抵消了成骨 BMP 诱导骨祖细胞分化和骨化的能力。信号级联的启动涉及 BMP-3 与 II 型受体 ACVR2B 的结合，激活 SMAD2 依赖性和 SMAD 独立途径，包括 TAK1 和 JNK 途径。在结构上，BMP-3以二硫键连接的同二聚体形式存在，并与II型受体ACVR2B相互作用以发挥其调节功能。

Measured by its ability to inhibit BMP-2-induced alkaline phosphatase production by MC3T3-E1 mouse preosteoblast cells. 30 µg/mL of hBMP-3 will antagonize hBMP-2 (0.25 µg/mL) induction of alkaline phosphatase in MC3T3E1 cells by 52.83%.

Lyophilized from a 0.2 μm filtered solution of 4 mM HCL, pH 0.8, 5% trehalose, 5% mannitol and 0.01% Tween80.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 1 mg/mL in ddH₂O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
