General description

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 36.8 kDa homodimeric protein containing two 159 amino acid polypeptide subunits.

Physical form

Sterile filtered and then lyophilized from 5 mM Tris, pH 8.0 plus 80 mM Arginine.

Reconstitution

Centrifuge the vial prior to opening. Avoid freeze-thaw cycles.
Reconstitute in water to a concentration of 0.1-0.5 mg/mL. The solution can then be diluted into other aqueous buffers.
