CSF3 (G-CSF), Murine

GoldBio growth factors are manufactured for RESEARCH USE ONLY and cannot be sold for human consumption!Recombinant Murine Colony Stimulating Factor 3 (granulocyte) Granulocyte Colony-Stimulating Factor, G-CSFPluripoietinColony Stimulating Factor 3 (CSF3), formerly called granulocyte colony stimulating factor (G­CSF), is a pleiotropic cytokine. It is mainly produced by monocytes and macrophages upon activation by endotoxin, TNF­α and IFN­γ. Many cell types secreted this protein after LPS, IL1 or TNF­α activation, including fibroblasts, endothelial cells, astrocytes and bone marrow stromal cells. Various carcinoma cell lines and myeloblastic leukemia cells can express CSF3 constitutively. CSF3 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 monocytes­macrophages. In addition, it may function in some adhesion or recognition events at the cell surface. The murine CSF3 cDNA encodes a 208 amino acid residue precursor protein containing a 30 amino acid residue signal peptide that is proteolytically cleaved to generate the 178 amino acid residue mature protein. Murine CSF3 is 73% identical at the amino acid level to human CSF3 and the two proteins show species cross­reactivity.Sterile Filtered White lyophilized powder.
