  • Function

    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. CSF-1 induces cells of the monocyte/macrophage lineage. It plays a role in immunological defenses, bone metabolism, lipoproteins clearance, fertility and pregnancy.
  • Post-translational

    Glycosylation and proteolytic cleavage yield different soluble forms. A high molecular weight soluble form is a proteoglycan containing chondroitin sulfate.
    Isoform 1 is N- and O-glycosylated. Isoform 3 is N-glycosylated.
  • Cellular localization

  • Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of Human kidney tissue sections labeling M-CSF with Purified ab52864 at 1:500 dilution (1.52 µg/ml). Heat mediated antigen retrieval was performed using ab93684 (Tris/EDTA buffer, pH 9.0)

  • Immunocytochemistry/ Immunofluorescence analysis of THP-1 (Human monocytic leukemia monocyte) cells labeling M-CSF with Purified ab52864 at 1:100 (7.6 µg/ml). Cells were fixed in 100% Methanol and permeabilized with None. Cells were counterstained with Ab195889 Anti-alpha Tubulin antibody [DM1A] - Microtubule Marker (Alexa Fluor® 594) 1:200 (2.5 µg/ml). Goat anti rabbit IgG (Alexa Fluor® 488, ab150077) was used as the secondary antibody at 1:1000 (2 µg/ml) dilution. DAPI nuclear counterstain. PBS instead of the primary antibody was used as the secondary antibody only control.

Customer reviews and Q&As


I can confirm to you that it is reported in literature that M-CSF can also be detected in a 45 kDa form (see links below)


https://www.researchgate.net/publication/14333823_Macrophage_colony_stimulating_factor_involvement_in_uremic_patients  (in the introduction section).

The size of the band is dependent on whether you are detecting the circulating or membrane bound form.

I hope you found this information helpful and I am happy to answer any further questions or concerns you have.  The antibody is covered by the Abpromise guarantee.
