About This Kit
The Human Interleukin-9 (Hu IL-9) ELISA quantitates Hu IL-9 in human serum, plasma, buffered solution, or cell culture medium. The assay will exclusively recognize both natural and recombinant Hu IL-9.
Principle of the method
The Human IL-9 solid-phase sandwich ELISA (enzyme-linked immunosorbent assay) is designed to measure the amount of the target bound between a matched antibody pair. A target-specific antibody has been pre-coated in the wells of the supplied microplate. Samples, standards, or controls are then added into these wells and bind to the immobilized (capture) antibody. The sandwich is formed by the addition of the second (detector) antibody, a substrate solution is added that reacts with the enzyme-antibody-target complex to produce measurable signal. The intensity of this signal is directly proportional to the concentration of target present in the original specimen.
Rigorous validation
Each manufactured lot of this ELISA kit is quality tested for criteria such as sensitivity, specificity, precision, and lot-to-lot consistency. See manual for more information on validation.
Target information
Interleukin 9 (IL-9) is produced by activated T helper 2 (Th2) lymphocytes. IL-9 regulates many cell types involved in classical Th2-associated asthma responses, including B and T lymphocytes, mast cells, eosinophils, and epithelial cells. The mouse IL-9 cDNA encodes a 144 amino acid precursor protein with an 18 amino acid signal peptide that is cleaved to form the mature cysteine-rich protein with a molecular mass of 14 kDa. Native mouse IL-9 is heavily glycosylated. Recently, TGF beta has been reported to play an important role in the differentiation of IL-17-producing T helper cells and inducible regulatory T cells by reprogramming Th2 cells to secrete IL-9, thereby driving the differentiation of Th9 cells directly.
