PDGF-BB 蛋白, Rat (His)

PDGF-BB Protein, Rat is a member of PDGF family, which promotes cell proliferation, survival and migration, through binding to the tyrosine kinase PDGF receptor.

血小板衍生生长因子 (PDGF) 是间充质细胞和成骨细胞的有效促细胞分裂剂和化学引诱剂，可刺激血管生成分子，从而在骨再生中发挥重要作用^[1]。血小板衍生生长因子-BB是PDGF家族的成员，通过与酪氨酸激酶PDGF受体结合促进细胞增殖、存活和迁移。PDGF-BB对失血性休克发挥有益作用，这与靶向CX43改善血管反应性和血流动力学密切相关。PDGF-BB 通过与 PDGFR 结合在海绵体平滑肌细胞 (CCSMC) 中发挥作用^[2]。

Measured in a cell proliferation assay using NIH‑3T3 mouse fibroblast cells. The ED₅₀ for this effect is 5.465 ng/mL, corresponding to a specific activity is 1.83×10⁵ units/mg.

  Greater than 95% as determined by reducing SDS-PAGE

无菌粉末.

Lyophilized from a 0.2 μm filtered solution of 50 mM Tris-HCL, 300 mM NaCl, 200 mM arginine, pH 7.4.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/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.
