Human Interleukin 9 (IL-9) ELISA Kit

Interleukin-9 (IL-9) is a pleiotropic cytokine secreted primarily by Th9 and Th2 lymphocytes. It drives mast cell proliferation, IgE class switching, and goblet cell hyperplasia, making it a key target in asthma, atopic dermatitis, and parasite clearance research.

This quantitative immunoassay from Assay Genie enables sensitive detection of endogenous IL-9 in human specimens, supporting investigations in allergy, mucosal immunity, and tumor microenvironment biology.

The kit includes a pre-coated microplate, lyophilized standards, biotinylated detection antibody, streptavidin-HRP conjugate, and TMB substrate. Researchers load 100 uL of standard or diluted sample per well, incubate the plate at room temperature, and quantify results by absorbance measurement. Unopened reagents should be stored at 4°C and the conjugate kept protected from light; this product is intended for research use only.
