SCF 蛋白, Human

SCF, Human, as a recombinant protein, plays essential roles in gametogenesis, melanogenesis and hematopoiesis. SCF, Human also plays an important role in nervous system.

干细胞因子（SCF）也称为肥大细胞生长因子（MGF）和钢因子（SLF），在配子发生、黑素生成和造血早期阶段发挥重要作用。SCF是一种二聚体分子，通过结合并激活受体酪氨酸激酶c-Kit^[1][2]来发挥其生物学功能。

Measured in a cell proliferation assay using TF-1 human erythroleukemic cells. The ED50 for this effect is 1-5 ng/mL, corresponding to a specific activity is > 2×10^5 units/mg.

  Greater than 95% as determined by reducing SDS-PAGE.

无菌粉末.

Lyophilized from a 0.2 μm filtered solution of 20 mM PB, 150 mM NaCl, pH 7.0 or 50 mM Tris-HCL, 300 mM NaCL, pH 8.0.

<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.
