M-CSF was first characterized as a glycoprotein that induces monocyte and macrophage colony formation from precursors in murine bone marrow cultures. M-CSF binds CD14+ monocytes and promotes the survival/proliferation of peripheral blood monocytes. In addition, M-CSF enhances inducible monocyte functions including phagocytic activity, microbial killing, and cytotoxicity for tumor cells as well as induces the synthesis of inflammatory cytokines such as IL-1, TNFα, and IFNγ in monocytes.
Multiple CSF1 mRNA species have been described that arise from alternative splicing in exon 6 and the alternative use of the 3’ end of exons 9 or 10. As a result, two distinct CSF1 protein products are encoded by these transcripts: a cell-surface or membrane-bound form of CSF1 (mCSF1) and a soluble form (sCSF1). Uterine sCSF1 is highly increased during pregnancy. On the contrary, uterine mCSF1 remains low during pregnancy. High levels of M-CSF have been associated to 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. Mouse M-CSF and IL-34 exhibit cross-species specificity, both bind to the human and mouse M-CSF receptors. IL-34 can regulate myeloid development and substitute for CSF-1 in vivo. IL-34 has overlapping but not identical biological activities as M-CSF.
Product Details
- Source
- Mouse M-CSF, amino acids Lys33-Glu262 (Accession# NM_001113530.1) was expressed in 293E cells.
- Molecular Mass
- The 251 amino acid recombinant protein has a predicted molecular mass of approximately 28.2 kD. The DTT-reduced and non-reduced protein migrate at approximately 50 kD and 100 kD respectively by SDS-PAGE. The N-terminal contains a His9-(SGGG)2-IEGR-tag.
- Purity
- >98%, as determined by Coomassie stained SDS-PAGE.
- Formulation
- 0.22 µm filtered protein solution is in PBS.
- Endotoxin Level
- Less than 0.01 ng per µg cytokine as determined by the LAL method.
- Concentration
- 10 and 25 µg sizes are bottled at 200 µg/mL. 100 µg size and larger sizes are lot-specific and bottled at the concentration indicated on the vial. To obtain lot-specific concentration and expiration, please enter the lot number in our Certificate of Analysis online tool.
- 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% 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 and stored at -20°C or colder for up to 3 months. Avoid repeated freeze/thaw cycles.
- Activity
- ED50 =2 - 6 ng/ml, corresponding to a specific activity of 1.6 - 5 x 105 units/mg, as determined by M-NFS60 cell proliferation induced by mouse M-CSF in a dose dependent manner.

Antigen Details
- Structure
- Disulfide-linked glycosylated homodimer.
- Distribution
-
M-CSF is broadly expressed in adult mouse tissues. M-CSF is released by fibroblasts, breast cancer cell lines, alveolar macrophages, stromal bone marrow cells, endothelial cells, and mesenchymal cells.
- Function
- M-CSF is the key regulator of the survival, proliferation, and differentiation of mononuclear phagocytes and plays a central role in the regulation of osteoclastogenesis. CSF-1 also regulates the development of Paneth cells, Langerhans cells, lamina propria dendritic cells, and microglia.
- Interaction
- Monocytes, macrophages, mononuclear phagocyte precursors, microglia, proliferating smooth muscle cells, umbilical vein endothelial cells, and breast cancer cell lines.
- Ligand/Receptor
- M-CSFR or CSF1R (CD115)
- Cell Type
- Embryonic Stem Cells, Hematopoietic stem and progenitors
- Biology Area
- Cell Biology, Cell Proliferation and Viability, Immunology, Stem Cells
