It is recommended to reconstitute the lyophilized Recombinant Human Granulocyte Colony Stimulating Factor (G-CSF) in sterile 18 M-omega-cm H2O not less than 100 myg/ml, which can then be further diluted to other aqueous solutions. Quantitation Protein quantitation was carried out by two independent methods:1. UV spectroscopy at 280 nm using the absorbency value of 0.815 as the extinction coefficient for a 0.1% (1 mg/ml) solution. This value is calculated by the PC GENE computer analysis program of protein sequences (IntelliGenetics).2. Analysis by RP-HPLC, using a standard solution of recombinant G-CSF as a Reference Standard.

Human Granulocyte Colony Stimulating Factor (G-CSF) contains internal disulfide bonds. Among the family of colony-stimulating factors, Granulocyte Colony Stimulating Factor (G-CSF) is the most potent inducer of terminal differentiation to granulocytes and macrophages of leukemic myeloid cell lines. The synthesis of Granulocyte Colony Stimulating Factor (G-CSF) can be induced by bacterial endotoxins, TNF, Interleukin-1 and GM-CSF. Prostaglandin E2 inhibits the synthesis of Granulocyte Colony Stimulating Factor (G-CSF). In epithelial, endothelial, and fibroblastic cells secretion of Granulocyte Colony Stimulating Factor (G-CSF) is induced by Interleukin-17. Recombinant Human Granulocyte Colony Stimulating Factor (G-CSF) produced in E. coli is a single, non-glycosylated, polypeptide chain containing 175 amino acids and having a molecular mass of 18,800 Da. Synonym: rHuG-CSF, G-CS. Formulation: The protein was lyophilized after extensive dialysis against 10mM HAc-NaAc, pH4.0, 150mM NaCl, 0.004% Tween 80, 5% Mannitol buffer.
