Specificity:

Armenian Hamster Anti-Mouse IL-1 R1 (Clone JAMA-147) recognizes Mouse IL-1 R1. This monoclonal antibody was purified using multi-step affinity chromatography methods such as Protein A or G depending on the species and isotype.

Background:

IL-1 binds two receptors, IL-1RI and IL-1RII. The ligands IL-1α and IL-1ß exert all of their various biological actions by binding IL-1RI. IL-1RII has a shortened cytoplasmic domain that is unable to transduce signals and therefore acts as a decoy receptor and competitively antagonizes the binding of IL-1α and IL-1ß, thereby reducing their biological effects. Binding of the ligands to IL-1RI is enhanced by an accessory protein, IL-1R-AcP. IL-1RI is expressed on T cells, thymocytes, dendritic cells, fibroblasts, vascular endothelial cells, epithelial cells and neural cells. It is an 80 kD transmembrane glycoprotein.

R-phycoerythrin (R-PE) has a molecular weight of 240 kDa and is purified from red algae. R-PE is an intensely bright phycobiliprotein with an absorption maxima at approximately 496, 546 and 565 nm, and a fluorescence emission maximum of ~578 nm.
