JES1-5A10

The JES1-5A10 monoclonal antibody specifically binds to the human Interleukin-5 (IL-5). IL-5 is a cytokine that is also known as T-cell replacing factor (TRF), Eosinophil differentiation factor (EDF), and B cell differentiation factor I. IL-5 is produced by T cells, mast cells, and eosinophils. IL-5 controls the generation, differentiation, activation and localization of eosinophils. IL-5 also activates and promotes the differentiation of basophils. IL-5 plays an important role in regulating cell-mediated immunity against parasitic infections and some tumors. High level IL-5 production is involved in some allergic diseases including asthma. IL-5 exerts its biological effects by binding to and signaling through high-affinity heterodimeric IL-5 receptors comprised of transmembrane IL-5 receptor alpha (IL-5Rα, aka, CD125) and beta common (βc, aka, CD131) chains. The βc chain serves as the common signaling subunit for the IL-5 receptor heterodimer as well as for the heterodimeric IL-3 and GM-CSF receptors. The immunogen used to generate the JES1-5A10 hybridoma was recombinant human IL-5. The JES1-5A10 antibody has been reported to cross react with IL-5 from rhesus monkey. This is a neutralizing antibody.

NA/LE
NA/LE refers to the culture and purification methods and buffer used to produce purified antibodies with no azide and low endotoxin: Aqueous buffered solution containing no preservative, 0.2µm sterile filtered. Endotoxin level is ≤0.01 EU/µg (≤0.001 ng/µg) of protein as determined by the LAL assay.NA/LE are perfectly suited to be used in culture or in vivo (for nonhuman studies) for functional assays — blocking, neutralizing, activation or depletion — where the presence of azide may damage cells or exogenous endotoxin may signal or activate cells.
