RecombinantG-CSF, Rat

• Description:

  Granulocyte Colony-Stimulating Factor (G-CSF) is a hematopoietic cytokine belonging to the four-helix bundle cytokine superfamily. G-CSF is produced by monocytes, macrophages, fibroblasts, and endothelial cells. Its expression is highly regulated and induced by a variety of agents, including Tumor Necrosis Factor (TNF), Interleukin-1 (IL-1), Interferon γ (IFN-γ), and Granulocyte-Macrophage Colony-Stimulating Factor (GM-CSF) . G-CSF binds to the CSF-specific high affinity receptors expressed on neutrophilic granulocyte lineage. In vivo G-CSF regulates the production of neutrophilic granulocytes, a critical part of host defense systems, and helps the maturation of leukemic cell lines. G-CSF is widely employed clinically because of its fairly innocuous safety profile.Recombinant rat Granulocyte Colony-Stimulating Factor (rrG-CSF) produced in E.coli is a single non-glycosylated polypeptide chain containing of 194 amino acids. A fully biologically active molecule, rrG-CSF has a molecular mass of 21.4 kDa analyzed by non-reducing SDS-PAGE and is obtained by proprietary chromatographic techniques at GenScript.
