It is mainly produced by monocytes and macrophages upon activation by endotoxin, TNF-α and IFN-γ. Besides, many other cell types can secreted this protein after LPS, IL-1 or TNF-α activation, which are fibroblasts, endothelial cells, astrocytes and bone marrow stromal cells. Various carcinoma cell lines and myeloblastic leukemia cells can express G-CSF constitutively. G-CSF is cytokine that acts in hematopoiesis by controlling the production, differentiation, and function of 2 related white cell populations of the blood, the granulocytes and the monocytes-macrophages. In addition it may function in some adhesion or recognition events at the cell surface. In humans, two distinct cDNA clones for G-CSF, encoding 207 and 204 amino acid (a.a.) precursor proteins, have been isolated. Both proteins have a 30 a.a. signal peptide and have identical amino acid sequences except for a three a.a. insertion (deletion) at the 35th a.a. residue from the N-terminus of the mature protein. Human G-CSF is 73 % identical at the amino acid level to Mouse G-CSF and the two proteins show species cross-reactivity.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eResearch_area\u003c\/b\u003e:Immunology\u003c\/p\u003e\u003cp\u003e\u003cb\u003ePurity\u003c\/b\u003e:\u0026gt; 98 % by SDS-PAGE and HPLC analyses.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eSource\u003c\/b\u003e:Escherichia coli.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFull product name\u003c\/b\u003e:Recombinant Human Granulocyte Colony Stimulating Factor\u003c\/p\u003e\u003cp\u003e\u003cb\u003eBiological activity\u003c\/b\u003e:Fully biologically active when compared to standard.
