Murine GM-CSF, 18-141 aa, Recombinant, E. coli Full name: Granulocyte-macrophage colony stimulating factor 2 NCBI Accession: NP_034099 GM-CSF is a hematopoietic growth factor that stimulates the development of neutrophils and macrophages and promotes the proliferation and development of early erythroid megakaryocytic and eosinophilic progenitor cells. It is produced in by endothelial cells, monocytes, fibroblasts and T-lymphocytes. GM-CSF inhibits neutrophil migration and enhances the functional activity of the mature end-cells. Mouse GM-CSF protein is 125 amino acids and shares approximately 60% homology with the human GM-CSF protein. Recombinant mouse GM-CSF was expressed in E. coli and purified by conventional chromatography, after refolding of the isolated inclusion bodies in a renaturation buffer. Molecular Weight: 14kD (125 aa) Sequence: MAPTRSPITV TRPWKHVEAI KEALNLLDDM PVTLNEEVEV VSNEFSFKKL TCVQTRLKIF EQGLRGNFTK LKGALNMTAS YYQTYCPPTP ETDCETQVTT YADFIDSLKT FLTDIPFECK KPVQK Biological Activity: Measured in a cell proliferation assay using MC/9 cells. The ED50 for this effect is less or equal to 0.5 ng/ml. Storage and Stability: May be stored at 4C for short-term only. For long-term storage, aliquot and store at -20C. Aliquots are stable for at least 6 months at -20C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
