Granulocyte/Macrophage Colony-Stimulating Factor, Recombinant, Rat, Animal Free (GM-CSF, CSF-2, MGI-1GM, pluripoietin-alpha)

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. The human and murine molecules are species-specific and exhibit no cross-species reactivity. Recombinant rat GM-CSF is a 14.5kD globular protein consisting of 128 amino acids residues.
