Porcine GM-CSF Antibody Summary

Species Reactivity
Porcine
Specificity
Detects porcine GM-CSF in direct ELISAs and Western blots. In direct ELISAs and Western blots (reducing conditions), approximately 20% cross‑reactivity with recombinant rat GM-CSF is observed and less than 1% cross-reactivity with recombinant human GM-CSF and recombinant mouse GM-CSF is observed.
Source
Monoclonal Mouse IgG1 Clone # 111802
Purification
Protein A or G purified from ascites
Immunogen
E. coli-derived recombinant porcine GM-CSF
Ala18-Lys144
Accession # Q29118
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 Porcine GM-CSF (Catalog # 711-PG)
Neutralization
Measured by its ability to neutralize GM‑CSF-induced proliferation in the TF‑1 human erythroleukemic cell line. Kitamura, T. et al. (1989) J. Cell Physiol. 140:323. The Neutralization Dose (ND50) is typically 1-4 µg/mL in the presence of 40 ng/mL Recombinant Porcine 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 Porcine GM‑CSF Antibody. Recombinant Porcine GM-CSF (Catalog # 711-PG) stimulates proliferation in the TF-1 human erythroleukemic cell line in a dose-dependent manner (orange line). Proliferation elicited by Recombinant Porcine GM-CSF (40 ng/mL) is neutralized (green line) by increasing concen-trations of Mouse Anti-Porcine GM-CSF Monoclonal Antibody (Catalog # MAB711). The ND50 is typically 1-4 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 porcine GM-CSF shares 61%‑72% amino acid sequence identity with canine, feline, human, and rat GM-CSF and 53% 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 (11, 12). In addition, GM-CSF binds a naturally occurring soluble form of GM-CSF R alpha (13). The activity of GM-CSF is species specific between human and mouse (14).
