Background: M-CSF

Macrophage Colony Stimulating Factor (M-CSF), also named CSF-1, is a hematopoietic growth factor that is involved in the proliferation, differentiation, and survival of monocytes, macrophages, and bone marrow progenitor cells. It is produced by osteoblasts (as a result of endocrine stimulation by parathyroid hormone) exerts paracrine effects on osteoclasts and can interact with CSF1R. M-CSF is a four alpha-helical bundle cytokine and its active form is found extracellularly as a disulfide-linked homodimer. Four transcript variants encoding three different isoforms have been reported for M-CSF gene. Although forms may vary, all of them contain the N-terminal 150 a.a. portion that is necessary and sufficient for interaction with the receptor. The first 223 a.a. of mature human M-CSF shares 88 %, 86 %, 81 % and 74 % sequence identity with corresponding regions of dog, cow, mouse and rat M-CSF, respectively. Human M-CSF is active in the mouse, but mouse M-CSF is reported to be species-specific.

FAQs for Recombinant Human M-CSF Protein

Showing  1 - 1 of 1 FAQ Showing All

  • Q: Hi I'm looking at product NBP2-34975, I was wondering if I could do a lower concentration reconsistution?

    A: We recommend reconstitution to 0.1mg/ml, but if a different concentration would work for you, you can of course do that. We do recommend reconstituting and then aliquoting out tubes to avoid freeze-thaw cycles.
