About This Kit
The Human Interleukin 13 (Hu IL-13) ELISA quantitates Hu IL-13 in human serum, plasma, cell culture supernatants or other body fluids. The assay will exclusively recognize both natural and recombinant Hu IL-13.
Principle of the method
The Human IL-13 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 or controls are then added into these wells and bind to the immobilized (capture) antibody. The sandwich is formed by the binding of the second (detector) antibody to the target on a different epitope from the capture antibody. An antibody conjugated with enzyme binds the formed sandwich. After incubation and washing steps to rid the microplate of unbound substances, 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
IL-13 is an immunoregulatory cytokine produced primarily by activated Th2 cells, and is involved in regulating inflammatory and immune responses. IL-13 down-regulates macrophage activity, thereby inhibiting the production of pro-inflammatory cytokines and chemokines, and is involved in allergen-induced asthma through mechanisms independent of IgE and eosinophils. IL-13 also regulates several stages of B cell maturation and differentiation, up-regulates CD23 and MHC class II expression, and promotes IgE isotype switching of B cells. Structurally, IL-13 closely resembles IL-3, IL-4, IL-5 and GM-CSF. The gene encoding IL-13, IL3, IL5, IL4, and CSF2 form a cytokine gene cluster on chromosome 5q, with the IL-13 gene particularly close to IL4.
