Mouse Interleukin 17 (IL-17) ELISA Kit

This assay employs a two-site sandwich ELISA to quantitate IL17A in samples. An antibody specific for IL17A has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any IL17A present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for IL17A is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of IL17A bound in the initial step. The color development is stopped and the intensity of the color is measured.
 

Interleukin 17 (IL-17; also known as IL-17A) is a 30 - 35 kDa variably glycosylated homodimeric protein that belongs to a unique family of cysteine-knot related proteins. Its sequence was originally isolated from an activated rodent hybridoma and termed CTLA-8 . It is synthesized as a 155 amino acid (aa) precursor that contains a 23 aa signal sequence and a 15 kDa, 132 aa mature segment. Although there are two intrachain disulfide bonds that create a ring reminiscent of those found in cysteine-knot proteins, the actual closed knot structure does not appear to form. IL-17 has one potential N-linked glycosylation site.IL-17, a T cell-derived proinf lammatory cytokine, is produced by TCR
