Canine GM-CSF

Description :
FAQ COA 已发表文献 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 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 Canine GM-CSF is a 14.5 kDa globular protein consisting of 127 amino acids, containing two intramolecular disulfide bonds and two potential N-linked glycosylation sites.
