General description

Product Source: E. coli

Granulocyte/Macrophage Colony-Stimulating Factor (GM-CSF) was initially characterized as a factor that can support the in vitro colony formation of granulocyte macrophage progenitors. It is also a growth factor for erythroid, megakaryocyte, and eosinophil progenitors. GMCSF is produced by a number of different cell types (including T cells, B cells, macrophages, mast cells, endothelial cells, fibroblasts, and adipocytes) in response to cytokine or inflammatory stimuli. The human and murine molecules are species-specific and exhibit no cross-species reactivity. Recombinant human GM-CSF is a 14.6 kDa globular protein consisting of 128 amino acids containing two intramolecular disulfide bonds and two potential N-linked glycosylation sites.
