Macrophage colony formation from precursors in murine bone marrow cultures. M-CSF is constitutively present at biologically active concentrations in human serum. It binds CD14+ monocytes and promotes the survival/proliferation of human peripheral blood monocytes. In addition, M-CSF enhances inducible monocyte functions including phagocytic activity, microbial killing, cytotoxicity for tumor cells as well as synthesis of inflammatory cytokines such as IL-1, TNF-α, and INF-γ in monocytes. M-CSF induces RANKL production in mature human osteoclasts; consequently, M-CSF is a potent stimulator of mature osteoclast resorbing activity. Also, M-CSF induces VEGF in human monocytes in human tumors; high levels of M-CSF, mononuclear phagocytes, and VEGF are associated with poor prognosis in patients with cancer. High levels of M-CSF have been associated with different pathologies such as pulmonary fibrosis and atherosclerosis. M-CSF binds to its receptor M-CSFR, and this receptor is shared by a second ligand, IL-34. Human M-CSF and IL-34 exhibit cross-species specificity – both bind to human and mouse M-CSF receptors.

- Source
- Human M-CSF, amino acids Glu33-Ser190 (Accession# NM_172212.2) was expressed in 293E cells.
- Molecular Mass
- The 179 amino acid recombinant protein has a predicted molecular mass of approximately 20.6 kD. The DTT-reduced and non-reduced protein migrate at approximately 25 - 35 kD and 55 - 70 kD respectively by SDS-PAGE. The N-terminal contains a His9-(SGGG)2-IEGR-tag.
- Purity
- > 95%, as determined by Coomassie stained SDS-PAGE
- Formulation
- 0.1 µm filtered protein solution is in PBS.
- Endotoxin Level
- Less than 0.1 EU per µg protein as determined by the LAL method
- Concentration
- 500 µg/mL
- Storage & Handling
- Unopened vial can be stored between 2°C and 8°C for up to 2 weeks, at -20°C for up to six months, or at -70°C or colder until the expiration date. For maximum results, quick spin vial prior to opening. The protein can be aliquoted and stored at -20°C or colder. Stock solutions can also be prepared at 50 - 100 µg/mL in appropriate sterile buffer, carrier protein such as 0.2 - 1% endotoxin-free BSA or HSA can be added when preparing the stock solution. Aliquots can be stored between 2°C and 8°C for up to one week or stored at -20°C or colder for up to 3 months. Avoid repeated freeze/thaw cycles.
- Activity
- ED50 = 0.5 - 2.0 ng/mL as measured by its ability to induce proliferation of M-NFS-60 mouse myelogenous leukemia lymphoblast cells.
