Protein A or G purified from ascites

Immunogen

E. coli-derived recombinant rat GM-CSF
Ala18-Lys144
Accession # P48750

Formulation

Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied either lyophilized or as a 0.2 µm filtered solution in PBS.

Applications

Recommended Concentration

Sample

Rat GM-CSF Sandwich Immunoassay

Recommended Concentration

Reagent

ELISA Capture (Matched Antibody Pair)

2-8 µg/mL

Use in combination with:

Detection Reagent: Rat GM-CSF Biotinylated Antibody (Catalog # BAF518)

Standard: Recombinant Rat GM-CSF Protein (Catalog # 518-GM)

Neutralization

Measured by its ability to neutralize GM‑CSF-induced proliferation in the DA3 mouse myeloma cell line. Ihle, J.N. et al. (1984) Advances in Viral Oncology. In G. Klein (eds): Raven Press, New York, NY. 4:95. The Neutralization Dose (ND₅₀) is typically 0.2-0.8 µg/mL in the presence of 0.5 ng/mL Recombinant Rat GM‑CSF.

Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.

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 # MAB518). The ND₅₀ is typically 0.2-0.8 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 (8-10). 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).
