Technical Data
Macrophage Colony Stimulating Factor, Recombinant, Human (M-CSF, CSF-1, Lanimostim, Macrophage colony-stimulating factor 1 precursor, MCSF, M-CSF, MGC31930)
Molecular Biology Storage: -20CShipping: Blue Ice
Macrophage Colony Stimulating Factor (M-CSF) is produced by various cell types, including fibroblasts, microphages, and endothelial cells. M-CSF is involved in both the development and function of monocytes/microphages. Recombinant human M-CSF is a 36.8kD homodimeric protein containing two 159 amino acid polypeptide subunits.
