Solubility: It is recommended to reconstitute the lyophilised G-CSF in sterile bidest H2O not less than 100 μg/ml, which can then be further diluted to other aqueous solutions. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Activity: ED50: < 0.1 ng/ml corresponding to a specific activity of 1.3 x 108 IU/mg, calculated by the dosedependant proliferation of murine NFS-60 indicator cells (measured by 3H-thymidine uptake).
G-CSF is a glycoprotein containing internal disulfide bonds. It induces the survival, proliferation, and differentiation of neutrophilic granulocyte precursor cells and functionally activates mature blood neutrophils. Among the family of colony-stimulating factors, G-CSF is the most potent inducer of terminal differentiation to granulocytes and macrophages of leukemic myeloid cell lines. The synthesis of G-CSF can be induced by bacterial endotoxins, TNF, Interleukin-1, and GM-CSF (cat.# PR-436 or PR-437). Prostaglandin E2 inhibits the synthesis of G-CSF. In epithelial, endothelial, and fibroblastic cells secretion of G-CSF is induced by Interleukin-17. Recombinant Human Granulocyte Colony Stimulating Factor is a glycosylated, polypeptide chain containing 174 amino acids and having a molecular mass of 20 kDa. Human G-CSF is purified by proprietary chromatographic techniques.
Endotoxin: Less than 0.1 ng/μg (IEU/μg) of G-CSF.
