Animal-Free G-CSF 蛋白, Human (His)

G-CSF, a pivotal cytokine, regulates hematopoiesis by controlling the production, differentiation, and function of granulocytes and monocytes-macrophages. This monomeric protein specifically promotes granulocyte development, playing a crucial role in immune system regulation and blood cell formation. Animal-Free G-CSF Protein, Human (His) is the recombinant human-derived animal-FreeG-CSF protein, expressed by E. coli , with N-His labeled tag. The total length of Animal-Free G-CSF Protein, Human (His) is 174 a.a., with molecular weight of ~19.48 kDa.

粒细胞/巨噬细胞集落刺激因子 (G-CSF) 是一种对造血至关重要的细胞因子，控制着两种关键白细胞群的产生、分化和功能：粒细胞和单核细胞-巨噬细胞。作为一种单体蛋白，G-CSF 特异性诱导粒细胞发育，有助于调节免疫系统和血细胞形成。

Measure by its ability to induce proliferation in NFS-60 cells. The ED₅₀ for this effect is <50 pg/mL. The specific activity of recombinant human G-CSF is >2 x 10⁷ IU/mg

无菌粉末.

Lyophilized from a solution containing 1X PBS, pH 7.4, trehalose.

<0.1 EU per 1 μg of the protein by the 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.
