Biochem/physiol Actions

M-CSF (macrophage colony-stimulating factor) is a key regulator of cellular proliferation, differentiation, and survival of blood monocytes, tissue macrophages and their progenitor cells. M-CSF has been shown to play important roles in modulating dermal thickness, and male and female fertility. It is clinically used in the treatment of infection, malignancies and atherosclerosis. It facilitates hematopoietic recovery after bone marrow transplantation. M-CSF also works as a pleiotropic growth factor and plays a crucial role in reproduction and organogenesis. Absence of it can result in reduced growth, neurological and reproductive problems as well as developmental defects in the mammary gland, bone and pancreas.

M-CSF is a potent hematopoietic factor produced by a variety of cells including lymphocytes, monocytes, fibroblasts, endothelial cells, myoblasts and osteoblasts. Recombinant murine M-CSF is a 36.4 kDa homodimeric protein containing two 156 amino acid polypeptide subunits.

General description

M-CSF (macrophage colony-stimulating factor) is a potent hematopoietic factor produced by a variety of cells including lymphocytes, monocytes, fibroblasts, endothelial cells, myoblasts and osteoblasts. The protein works through its receptor CSF1R (colony stimulating factor 1 receptor). The human is reactive in murine systems, but the murine molecule exhibits no activity on human cells. Recombinant murine M-CSF is a 36.4kDa homodimeric protein containing two 156 amino acid polypeptide subunits.

Physical form

10 mM sodium phosphate, 50 mM sodium chloride, pH 7.5.

Reconstitution

Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1-0.5 mg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a stabilizer (example 5% Trehalose) and store in working aliquots at -20°C to -80°C.
