Name Recombinant Human M-CSF (CSF1) (E. coli)
Description M-CSF is produced by monocytes, granulocytes, endothelial cells, and fibroblasts. After cell activation, B cells and T cells and also a number of tumor cell lines are capable also of synthesizing this factor. M-CSF has been found to be synthesized by uterine epithelial cells in vivo. The M-CSF receptor is identical with the proto-oncogene fms. It has been renamed CD115. The receptor is a transmembrane protein with an extracellular ligand-binding domain of 512 amino acids, an intramembrane domain of 25 amino acids, and a cytoplasmic domain of 435 amino acids encoding a tyrosine kinase. Human M-CSF is active in mouse and rat cells. The murine factor is active in rat cells but inactive in human cells. M-CSF is a specific factor in that the proliferation inducing activity is more or less restricted to the macrophage lineage. M-CSF is a potent stimulator of functional activities of monocytes.

Species Human (H. sapiens)
Appearance Lyophilized Powder
Molecular Weight 18.5 kDa
Endotoxin Level <1.0 EU/µg of recombinant protein as determined by the LAL method
Purity >95% as determined by SDS-PAGE
Formulation Lyophilized from a 0.2 μm filtered solution in Tris and NaCl (pH 7.5)
Function The ED50 as determined by the dose-dependent stimulation of the proliferation of M-NFS-60 cells was found to be < 1.0 ng/mL
Reconstitution A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1 mg/mL. This solution can then be diluted into other buffers.
Storage The lyophilized protein is stable for at least one year from date of receipt at -70°C. Upon reconstitution, this cytokine can be stored in working aliquots at 2° - 8°C for one month, or at -20°C for six months, with a carrier protein without detectable loss of activity. Avoid repeated freeze/thaw cycles.
Usage For research use only. Not for diagnostic or therapeutic use.
