Scientific Data Images for Recombinant Human M-CSF Protein

Recombinant Human M‑CSF Protein SEC-MALS.

Recombinant human M-CSF (Catalog # 216-MC) has a molecular weight (MW) of 39.2 kDa as analyzed by SEC-MALS, suggesting that this protein is a homodimer.  MW may differ from predicted MW due to post-translational modifications (PTMs) present (i.e. Glycosylation).

Formulation, Preparation, and Storage

Carrier Free
What does CF mean?

CF stands for Carrier Free (CF). We typically add Bovine Serum Albumin (BSA) as a carrier protein to our recombinant proteins. Adding a carrier protein enhances protein stability, increases shelf-life, and allows the recombinant protein to be stored at a more dilute concentration. The carrier free version does not contain BSA.

What formulation is right for me?

In general, we advise purchasing the recombinant protein with BSA for use in cell or tissue culture, or as an ELISA standard. In contrast, the carrier free protein is recommended for applications, in which the presence of BSA could interfere.

Carrier: 216-MC

Background: M-CSF

M-CSF, also known as CSF-1, is a four-alpha -helical-bundle cytokine that is the primary regulator of macrophage survival, proliferation and differentiation (1-3). M-CSF is also essential for the survival and proliferation of osteoclast progenitors (1, 4). M-CSF also primes and enhances macrophage killing of tumor cells and microorganisms, regulates the release of cytokines and other inflammatory modulators from macrophages, and stimulates pinocytosis (2, 3). M-CSF increases during pregnancy to support implantation and growth of the decidua and placenta (5). Sources of M-CSF include fibroblasts, activated macrophages, endometrial secretory epithelium, bone marrow stromal cells and activated endothelial cells (1-5). The M-CSF receptor (c-fms) transduces its pleotropic effects and mediates its endocytosis. M-CSF mRNAs of various sizes occur (3-9). Full length human M-CSF transcripts encode a 522 amino acid (aa) type I transmembrane (TM) protein with a 464 aa extracellular region, a 21 aa TM domain, and a 37 aa cytoplasmic tail that forms a 140 kDa covalent dimer. Differential processing produces two proteolytically cleaved, secreted dimers. One is an N- and O- glycosylated 86 kDa dimer, while the other is modified by both glycosylation and chondroitin-sulfate proteoglycan (PG) to generate a 200 kDa subunit. Although PG-modified M-CSF can circulate, it may be immobilized by attachment to type V collagen (8). Shorter transcripts encode
M‑CSF that lacks cleavage and PG sites and produces an N-glycosylated 68 kDa TM dimer and a slowly produced 44 kDa secreted dimer (7). Although forms may vary in activity and half-life, all contain the N‑terminal 150 aa portion that is necessary and sufficient for interaction with the M-CSF receptor (10, 11). The first 223 aa of mature human M-CSF shares 88%, 86%, 81% and 74% aa identity with corresponding regions of dog, cow, mouse and rat M‑CSF, respectively (12, 13). 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 - 2 of 2 FAQs Showing All

  • Q: Does recombinant human M-CSF show activity in mouse cells?

    A: We evaluate the bioactivity of Recombinant Human M-CSF Protein (Catalog # 216-MC) in a cell proliferation assay using mouse myelogenous leukemia lymphoblast cells. Catalog # 216-MC exhibits an ED50 in the range of 0.5-1.5 ng/mL in this assay using mouse cells. We also offer the Recombinant Mouse M-CSF Protein (Catalog # 416-ML) for use in mouse assay systems.

  • Q: How long will recombinant human M-CSF last in cell culture?

    A: End-users will need to determine the appropriate concentration and timing when adding Recombinant Human M-CSF Proteins to cell culture experiments. The addition of protein may be dependent on certain culture conditions, including the cell number, density, and media content. For techniques and methodologies, we recommend reviewing our list of publications under the Citations tab on the product-specific web page to find reported use of our products in similar experimental layouts.
