  • Product overview

    Abcam’s IL-18 R beta (Interleukin-18 R beta) Human ELISA (Enzyme-Linked Immunosorbent Assay) kit is an in vitro enzyme-linked immunosorbent assay for the quantitative measurement of Human IL-18 R beta in serum, plasma, cell culture supernatants. (Human IL-18 R beta concentration is pretty low in normal serum/plasma, it may not be detected in this assay)

    This assay employs an antibody specific for Human IL-18 R beta coated on a 96- well plate. Standards and samples are pipetted into the wells and IL-18 R beta present in a sample is bound to the wells by the immobilized antibody. The wells are washed and biotinylated anti-Human IL-18 R beta 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-18 R beta bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.

  • Research areas
  • Function
    Required for the high affinity binding of interleukin 18 (IL-18) to its receptor complex (By similarity). Together with IL18R1 mediates IL-18-dependent activation of NF-kappa-B and JNK.
  • Tissue specificity
    Strongly expressed in peripheral blood leukocytes, spleen, lung, and, to a lesser extent, in colon, but not in any other tissue tested. Strongly expressed in T-cells polarized with IL-12. Specifically coexpressed with IL18R1 in Th1 cells.
  • Sequence similarities
    Belongs to the interleukin-1 receptor family.
    Contains 2 Ig-like C2-type (immunoglobulin-like) domains.
    Contains 1 TIR domain.
