IL5RA Antibody (PA5-47340) in Neu
Neutralization of IL5RA in TF‚1 human erythroleukemic cell line. Samples were incubated in IL5RA polyclonal antibody (Product # PA5-47340). Recombinant Human IL‚5 stimulates proliferation in the TF‚1 human erythroleukemic cell line in a dose-dependent manner (orange line). Proliferation elicited by Recombinant Human IL‚5 (0.5 ng/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Human IL‚5 Rα/CD125 Antigen Affinity-purified Polyclonal Antibody. The ND50 is typically 1-3 µg/mL.

Target Information
Interleukin 5 (IL-5) is a soluble T cell-derived factor, also known as T cell replacing factor (TRF), that induces B cell and eosinophil growth and differentiation. IL-5 exerts its biological activity through the IL-5 receptor (IL-5R), which is composed of two chains: an alpha chain that binds IL-5 with low affinity and a beta chain that does not bind IL-5, but together with the IL-5 alpha chain, constitutes the high affinity IL-5 receptor. The cytoplasmic domain of both the alpha and beta chains is essential for signal transduction. Specifically, the membrane-proximal proline-rich sequence of the cytoplasmic domain of the IL-5R receptor alpha subunit, IL-5Ralpha, is critical for the IL-5 induced proliferative response, expression of nuclear proto-oncogenes and tyrosine phosphorylation of cellular proteins, such as JAK1 and JAK2.
