Scientific Data Images for Human GM-CSF Antibody

Cell Proliferation Induced by GM‑CSF and Neutralization by Human GM‑CSF Antibody.

Cell Proliferation Induced by GM‑CSF and Neutralization by Human GM‑CSF Antibody.

Recombinant Human GM-CSF (Catalog # 215-GM) stimulates proliferation in the TF-1 human erythroleukemic cell line in a dose-dependent manner (orange line). Proliferation elicited by Recombinant Human GM-CSF (0.5 ng/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Human GM-CSF Antigen Affinity-purified Polyclonal Antibody (Catalog # AF-215-NA). The ND50 is typically 0.08-0.16 µg/mL.

Background: GM-CSF

GM-CSF was initially characterized as a factor that can support the in vitro colony formation of granulocyte-macrophage progenitors. It is also a growth factor for erythroid, megakaryocyte, and eosinophil progenitors. GM-CSF is produced by a number of different cell types (including T cells, B cells, macrophages, mast cells, endothelial cells, fibroblasts, and adipocytes) in response to cytokine or inflammatory stimuli. On mature hematopoietic cells, GM-CSF is a survival factor for and activates the effector functions of granulocytes, monocytes/macrophages, and eosinophils (1, 2). GM-CSF promotes a Th1 biased immune response, angiogenesis, allergic inflammation, and the development of autoimmunity (3‑5). It shows clinical effectiveness in ameliorating chemotherapy-induced neutropenia, and GM-CSF transfected tumor cells are utilized as cancer vaccines (6, 7). The 22 kDa glycosylated GM-CSF, similar to IL-3 and IL-5, is a cytokine with a core of four bundled alpha ‑helices (8‑12). Mature human GM-CSF shares 63%‑70% amino acid sequence identity with canine, feline, porcine, and rat GM-CSF and 54% with mouse GM-CSF. GM-CSF exerts its biological effects through a heterodimeric receptor complex composed of GM-CSF R alpha /CD116 and the signal transducing common beta  chain (CD131) which is also a component of the high-affinity receptors for IL-3 and IL-5 (13, 14). In addition, GM-CSF binds a naturally occurring soluble form of GM-CSF R alpha (15). Human GM-CSF is active on canine and feline cells but not on murine cells (16‑18).

    Published in https://www.ncbi.nlm.nih.gov/pubmed/28169287 Used at 10ug/ml. Briefly, frozen brain sections were fixed in 4% PFA (Fisher Scientific), followed by antigen retrieval using heating in acid citric buffer (Vector, Burlingame, CA, USA). Endogenous avidin-biotin was blocked for 15 min (Vector). Sections were incubated with 10% horse serum in PBS (Biosera, Boussens, France) and Fc Receptor Blocking Solution was added (Human TruStain FcX Biolegend, London, UK). Primary antibodies were added overnight at 4 °C. GM-CSF was detected with donkey anti-goat-biotin (ab6578, Abcam), followed by streptavidin-alkaline phosphatase (SA-5100, Vector) and visualised with the Vector Blue Alkaline Phosphatase Substrate Kit III (Vector).
