HGF 蛋白, Human (CHO)

HGF Protein, Human (CHO) is a cytokine binding to Met tyrosine kinase receptor, and exhibits biological activities.

肝细胞生长因子 (HGF) 通过 Met 酪氨酸激酶受体发挥生物活性。HGF 在各种组织的再生和保护免受损伤和病理中发挥作用。肾细胞中 Met 的基因破坏表明 HGF-Met 通路在肾细胞的增殖、形态发生和存活中发挥作用^[1]。

1.The ED₅₀ is <10 ng/mL as measured by 4MBr5 cells, corresponding to a specific activity of >1 × 10⁵ units/mg.
2.Measured by its ability to induce IL-11 secretion by Saos-2 human osteosarcoma cells. The ED₅₀ for this effect is 5.34 ng/mL, corresponding to a specific activity is 1.87×10⁵ U/mg.

  Greater than 95% as determined by reducing SDS-PAGE. Human HGF is initially produced as a single, inactive polypeptide and is subsequently cleaved by serine proteases to generate a 69-kDa α chain and a 34-kDa β chain. The free α and β chains then combine to form an active heterodimer through the formation of disulfide bonds between cysteine residues. Under reducing conditions (SDS-PAGE), the protein exhibits apparent molecular masses of 90, 60, and 34 kDa, which correspond to the heavy α chain and the light β chain, respectively, due to glycosylation.

Lyophilized after extensive dialysis against PBS. Or lyophilized from a 0.2 μm filtered solution of 20 mM PB, 150 mM NaCl, pH 7.4.

<0.2 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.
