Description

The Human Interleukin-29 (Hu IL-29) ELISA quantitates Hu IL-29 in human serum, plasma, buffered solution, or cell culture medium. The assay will exclusively recognize both natural and recombinant Hu IL-29. Principle of the method The Human IL-29 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.

IL-29 is a protein of the helical cytokine family and is a type III interferon sharing many functions with the type I family of interferons. The IL-29 gene is found on chromosome 19 in humans. It is also known as IFN-lambda1 and is highly similar in amino acid sequence to the IL-28, the other type III interferon. IL-29 does not bind the IFN-alpha/beta receptor, but instead signals through a receptor composed of the IL-28R1 and IL-10R2 subunits. Initial characterizations of the receptor demonstrated that it has a ubiquitous tissue distribution and is expressed on most non-hematopoietic cells.

Generation of native IL-29 is achieved by monocytes and dendritic cells in response to viral infection and stimulation with toll-like receptor ligands. IL-29 plays an important role in host defenses against microbes and its gene is highly upregulated in cells infected with viruses. IL 29 has significant antiviral activity and immunoregulatory properties and appears to inhibit T helper-2 (Th2) responses regarding inhibition of IL-13 production, compared with IL-4 or IL-5. The antiviral activities of IL-29 include the upregulation of MHC Class I expression on the cell surface and the expression of PKR. The ligand/receptor complex seems to signal through the Jak-STAT pathway.
