Macrophage colony-stimulating factor 1, also known as CSF-1, M-CSF, Lanimostim and CSF1, is a single-pass membrane protein which is disulfide-linked as a homodimer or heterodimer. Granulocyte / macrophage colony-stimulating factors are cytokines that act in hematopoiesis by controlling the production, differentiation, and function of 2 related white cell populations of the blood, the granulocytes and the monocytes-macrophages. M-CSF/CSF-1 is known to facilitate monocyte survival, monocyte-to-macrophage conversion, and macrophage proliferation. M-CSF/CSF-1 is a secreted cytokine which influences hemopoietic stem cells to differentiate into macrophages or other related cell types. It binds to the Colony stimulating factor 1 receptor. M-CSF/CSF-1 may also be involved in development of the placenta. The active form of M-CSF/CSF-1 is found extracellularly as a disulfide-linked homodimer, and is thought to be produced by proteolytic cleavage of membrane-bound precursors. M-CSF/CSF-1 induces cells of the monocyte/macrophage lineage. It also plays a role in immunological defenses, bone metabolism, lipoproteins clearance, fertility and pregnancy. Upregulation of M-CSF/CSF-1 in the infarcted myocardium may have an active role in healing not only through its effects on cells of monocyte/macrophage lineage, but also by regulating endothelial cell chemokine expression.

CSF1

Human Cells

A DNA sequence encoding the N-terminal fragment (Met 1-Asn 190) of human CSF1 (P09603-1) was fused with a polyhistidine tag at the C-terminus.Human and Cynomolgus CSF1 sequences are identical.

Human

The recombinant human CSF1 consists of 169 amino acids and predictes a molecular mass of 19.8 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rhCSF1 is approximately 27-32 kDa band due to glycosylation.

> 95 % as determined by SDS-PAGE

1. Measured by its binding ability in a functional ELISA.
2. Immobilized human CSF1R (Cat:503773) at 10 μg/mL (100 μl/well) can bind biotinylated human CSF-1 (Cat:501502).
The EC₅₀ of biotinylated human CSF-1 (Cat:501502) is 8 ng/mL.
3. Measured in a cell proliferation assay using M‑NFS‑60 mouse myelogenous leukemia lymphoblast cells.
The ED₅₀ for this effect is typically 0.4-2.3 ng/mL.
