Product overview
Human IL-22RA2 ELISA Kit is designed for the quantitative determination of IL-22RA2 in cell culture supernatants, plasma and serum samples.
This assay employs an antibody specific for human IL-22RA2 coated on a 96-well plate. Standards and samples are pipetted into the wells and IL-22RA2 present in a sample is bound to the wells by the immobilized antibody. The wells are washed and biotinylated anti-human IL-22RA2 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-22RA2 bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.

Function
Isoform 2 is a receptor for IL22. Binds to IL22, prevents interaction with the functional IL-22R complex and blocks the activity of IL22 (in vitro). May play an important role as an IL22 antagonist in the regulation of inflammatory responses.
Isoform 1 may play a role in establishing and maintaining successful pregnancy. -
Tissue specificity
Expressed in placenta, spleen, breast, skin and lung. Also detected in intestinal tract, testis, brain, heart and thymus. No expression found in prostate, bladder, kidney, ovary, muscle, bone marrow, liver and uterus. Isoform 1 is expressed only in placenta. Isoform 2 is expressed in placenta and breast and at lower level in spleen, skin, thymus and stomach. -
Sequence similarities
Belongs to the type II cytokine receptor family.
Contains 3 fibronectin type-III domains. -
