Rat GM-CSF Antibody Summary

Species Reactivity

Rat

Specificity

Detects rat GM-CSF in direct ELISAs and Western blots. In direct ELISAs and Western blots, no cross-reactivity with recombinant GM‑CSF from mouse, human, or pig is observed.

Source

Monoclonal Mouse IgG_2B Clone # 83308

Purification

Protein A or G purified from hybridoma culture supernatant

Immunogen

E. coli-derived recombinant rat GM-CSF
Ala1-Lys127
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.

Endotoxin Level

<0.10 EU per 1 μg of the antibody by the LAL method.

Applications

Recommended Concentration

Sample

Western Blot

1 µg/mL

Recombinant Rat GM-CSF (Catalog # 518-GM) under non-reducing conditions only. Catalog # AF518 is recommended to detect rat GM-CSF in Western blots.

CyTOF-ready

Ready to be labeled using established conjugation methods. No BSA or other carrier proteins that could interfere with conjugation.

Immunocytochemistry

8-25 µg/mL

See below

Intracellular Staining by Flow Cytometry

2.5 µg/10⁶ cells

Rat splenocytes fixed with paraformaldehyde and permeabilized with saponin

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 1-4 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.

Scientific Data

Neutralization

View Larger

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.

Immunocytochemistry

View Larger

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).
