Scientific Data Images for Rat GM‑CSF Antibody

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

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

Recombinant Rat GM-CSF (Catalog # 518-GM) stimulates proliferation in the DA3 mouse myeloma cell line in a dose-dependent manner (orange line). Proliferation elicited by Recombinant Rat GM-CSF (0.5 ng/mL) is neutralized (green line) by increasing concentrations of Rat GM-CSF Monoclonal Antibody (Catalog # MAB5181). The ND50 is typically 1-4 µg/mL.
GM-CSF antibody in Rat Splenocytes by Immunocytochemistry (ICC).

GM‑CSF in Rat Splenocytes.

GM-CSF was detected in immersion fixed rat splenocytes using Rat GM-CSF Monoclonal Antibody (Catalog # MAB5181) at 25 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm.

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 (8‑10). Mature rat GM-CSF shares 56%‑69% amino acid sequence identity with canine, feline, human, mouse, and porcine 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 (11, 12). In addition, GM-CSF binds a naturally occurring soluble form of GM‑CSF R alpha (13). Rat GM‑CSF is active on mouse cells, although mouse GM‑CSF is only weakly active on rat cells (14, 15).
