GM-CSF, human recombinant

Human GM-CSF (Granulocyte Macrophage Colony stimulating Factor) is a potent species-specific stimulator of bone marrow cells. GM-CSF stimulates precursor cells of granulocytes, macrophages and eosinophils. 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 containing 128 amino acid residues.
