U-PLEX Human IL-9 Assay

U-PLEX Human IL-9 Assay Overview
The U-PLEX Human IL-9 Assay maximizes your flexibility to design an experiment that measures IL-9 alone or multiplexed with other MSD U-PLEX assays, your own antibody pairs, or a combination of both. This assay accurately quantitates native and recombinant human IL-9 in multiple sample types. To learn more about the advantages of U-PLEX assays click here.

Description - Human interleukin 9 (HP40, P40; Gene ID: 3578) is a pleiotropic cytokine that has effects on both myeloid and lymphoid cells. It is produced by at least 2 subtypes of T helper cells. Th2 cells were the first cell type that was recognized to produce IL-9. Recently Th17 T cells have been found to secrete IL-9. Naïve T cells treated with TGF-β and IL-4 differentiate into the TH9 subtype. IL-9 binds to its cognate receptor IL9R, also known as CD129, which activates the JAK/STAT network.

Disease Focus/Application Area - Allergen-induced inflammation, extracellular parasites, asthma, and cancer.
