GH/Somatotropin 蛋白, Human (CHO)

GH Protein, Human (CHO) is a peptide hormone that stimulates growth, cell reproduction, and cell regeneration, which can be used for the treatment of growth disorders in children.

重组人生长激素是一种刺激生长、细胞繁殖和细胞再生的肽类激素，可用于治疗儿童生长障碍^[1]。生长激素是一种应激激素，可刺激 IGF-1 的产生并提高葡萄糖和游离脂肪酸的浓度^[2]。生长激素通过与靶细胞上的受体结合来发挥其部分作用，激活 MAPK/ERK 通路^[3]。

1. The ED₅₀ is <0.5 ng/mL as measured by murine Balb/c 3T3 cells, corresponding to a specific activity of >2 × 10⁶ units/mg.
2. ED₅₀ is < 0.5 ng/mL, as measured by a cell proliferation assay using Nb2-11 cells, corresponding to a specific activity of > 2.0 × 10⁶ units/mg

20-24 kDa

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

无菌粉末

Lyophilized after extensive dialysis against PBS.

<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.
