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.

IFN-lambdas constitute a novel family of interferons that mediate the induction of anti-viral protection in a wide variety of cells. There are three members in this family, namely lambda1, lambda2, and lambda3, which are also known as IL-29, IL-28A, and IL-28B, respectively. Similar to type I IFNs, IFN-lambdas activate an intracellular signaling to promote gene expression. IFN-lambdas mediate their anti-viral protection through a class II cytokine receptor complex composed of two essential receptor proteins, CRF2-12/IFN-lambdaR1, which is unique to IFN-lambdas, and CFR2-4/IL-10R2, which is shared with IL-10, IL-22, and IL-26 receptors. The IFN-lambdas, IL-28 and IL-29, have recently been reported to prime dendritic cells to induce proliferation of Foxp3-bearing regulatory T cells. DCs that differentiate in response to IFN-lambdas express high levels of class I and II MHC gene products, but low levels of costimulatory molecules. Moreover, these cells can specifically induce IL-2-dependent proliferation of CD4+CD25+FOXP3+ T cells with contact-dependent suppressive activity.
