Scientific Data Images for Human M-CSF Antibody

Cell Proliferation Induced by M-CSF and Neutralization by Human M-CSF Antibody.

Cell Proliferation Induced by M-CSF and Neutralization by Human M-CSF Antibody.

Recombinant Human M-CSF (Catalog # 216-MC) stimulates proliferation in the M-NFS-60 mouse myelogenous leukemia lymphoblast cell line in a dose-dependent manner (orange line). Proliferation elicited by Recombinant Human M-CSF (2.5 ng/mL) is neutralized (green line) by increasing concentrations of Human M-CSF Monoclonal Antibody (Catalog # MAB216). The ND50 is typically 0.005-0.020 µg/mL.

Applications for Human M-CSF Antibody

Application
Recommended Usage

Western Blot

1 µg/mL
Sample: Recombinant Human M-CSF (Catalog # 216-MC)
under non-reducing conditions only

Neutralization

Measured by its ability to neutralize M-CSF-induced proliferation in the M-NFS-60 mouse myelogenous leukemia lymphoblast cell line. Halenbeck, R. et al. (1989) Biotechnology 7:710. The Neutralization Dose (ND50) is typically 0.005-0.020 µg/mL in the presence of 2.5 ng/mL Recombinant Human M-CSF.
Please Note: Optimal dilutions of this antibody should be experimentally determined.

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. M-CSF is also essential for the survival and proliferation of osteoclast progenitors. 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. M-CSF increases during pregnancy to support implantation and growth of the decidua and placenta. Sources of M-CSF include fibroblasts, activated macrophages, endometrial secretory epithelium, bone marrow stromal cells and activated endothelial cells. The M-CSF receptor (c-fms) transduces its pleotropic effects and mediates its endocytosis. M-CSF mRNAs of various sizes occur. 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. Shorter transcripts encode M-CSF that lack cleavage and PG sites and produce an N-glycosylated 68 kDa TM dimer and a slowly produced 44 kDa secreted dimer. 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. 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. Human M-CSF is active in the mouse, but mouse M-CSF is reported to be species-specific.
