Human Interleukin-9 ELISA Kit

Quantify human Interleukin-9 (IL-9) in research samples with this 192-test ELISA kit from Antibodies.com. IL-9 is a pleiotropic cytokine secreted by Th2 and Th9 CD4+ T cell subsets, with documented roles in allergic inflammation, asthma pathophysiology, parasite defense responses, and tumor immunology research.

Configured for 192 individual determinations across two microplate runs, the kit supports higher-throughput cytokine quantification across experimental cohorts. The protocol uses matched antibody pairs to capture IL-9 from prepared samples, with chromogenic readout on a standard absorbance plate reader.

Intended for research use only, this assay is used with cell culture supernatant samples to study Th9 effector function, mast cell activation, and cytokine signaling in inflammatory disease models.

Store kit components refrigerated and equilibrate to room temperature before use.
