Recombinant Rat M-CSF

Macrophage colony-stimulating factor, or M-CSF, is a secreted cytokine which influences hemopoietic stem cells to differentiate into macrophages or other related cell types. M-CSF is a key regulator of cellular proliferation, differentiation, and survival of blood monocytes, tissue macrophages and their progenitor cells. It enhances cytotoxicity, superoxide production, phagocytosis, chemotaxis, and secondary cytokine production in monocytes and macrophages.¹ It binds to the Colony stimulating factor 1 receptor. M-CSF is known as one of the factors essential for osteoclast development.²

The biological activity of Rat Macrophage Colony Stimulating Factor is determined by the dose-dependent stimulation of the proliferation of murine M-NFS-60 cells. The ED₅₀ is 1 x 10⁵ units/mg.

Lyophilized

The molecular weight of Recombinant Rat M-CSF is Mr 18.1 kDa.

The lyophilized protein should be stored desiccated at -20°C. The reconstituted protein can be stored for at least one week at 4°C. For long-term storage of the reconstituted protein, aliquot into working volumes and store at -20°C in a manual defrost freezer. Avoid Repeated Freeze Thaw Cycles.
