Product information "Granulocyte Colony Stimulating Factor (G-CSF), human recombinant (rHuG-CSF), highly purified"
G-CSF is a hematopoietic growth factor that stimulates the development of committed progenitor cells to neutrophils and enhances the functional activities of the mature end-cell. It is produced in response to specific stimulation by a variety of cells including macrophages, fibroblasts, endothelial cells and bone marrow stroma. G-CSF is being used clinically to facilitate hematopoietic recovery after bone marrow transplantation. Human and murine G-CSF are cross-species reactive. Recombinant human G-CSF is an 18.7 kDa protein consisting of 174 amino acid residues. Biological Activity: The ED50 as determined by the dose-dependent stimulation of the proliferation of murine M-NFS-60 cells is < 0.1ng/ml, corresponding to a specific activity of > 1x10e7 units/mg.
