Target

  • 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
    modifications

    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.

    Question

    I've been using your antibody against M-CSF (ab52864). It says it is a 60kDa protein but is observed at 20kDa. When tested in my samples, this protein is coming up at around 45kDa. Have you seen this before? It is a very clean blot with only one specific band present so I do believe the antibody is very specific but just wondering if you have any advice in this case?

    Answer

    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.ncbi.nlm.nih.gov/pubmed/2179407

    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.
