产品概述
Human IL-1 R4 ELISA Kit (ST2) (ab100563) is an in vitro enzyme-linked immunosorbent assay for the quantitative measurement of Human IL-1 R4 in serum, plasma, and cell culture supernatants.
This assay employs an antibody specific for Human IL-1 R4 coated on a 96-well plate. Standards and samples are pipetted into the wells and IL-1 R4 present in a sample is bound to the wells by the immobilized antibody. The wells are washed and biotinylated anti-Human IL-1 R4 antibody is added. After washing away unbound biotinylated antibody, HRP-conjugated streptavidin is pipetted to the wells. The wells are again washed, a TMB substrate solution is added to the wells and color develops in proportion to the amount of IL-1 R4 bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.

ST2 is a member of a superfamily containing the Interleukin 1 (IL1) receptor and the Toll-like receptors (TLRs). The TLRs are signaling molecules that recognize different microbial products during infection and serve as an important link between the innate and adaptive immune responses. ST2 was originally identified as a protein whose production was stimulated by various proliferation-inducing agents such as PDGF and FGF. More recently, it has been shown to negatively regulate IL1 receptor and Toll-like receptor 4 (TLR4) signaling and to maintain endotoxin tolerance. It has been suggested that the inhibition of TLR4 signaling occurs through the association and sequestering of TLR adaptor molecules such as MyD88 and TIRAP. -
