  • Product overview

    Abcam's IL-13 Receptor alpha 2 Human ELISA Kit (ab193704) is an in vitro enzyme-linked immunosorbent assay for the quantitative measurement of human IL-13 Receptor alpha 2 in serum, plasma and cell culture supernatants.

    This assay employs an antibody specific for human IL-13 Receptor alpha 2 coated on a 96-well plate. Standards and samples are pipetted into the wells and the immobilized antibody captures IL-13 Receptor alpha 2 present in the samples. The wells are washed and biotinylated anti-human IL-13 Receptor alpha 2 antibody is added. After washing away any unbound biotinylated antibody, an HRP-conjugated streptavidin is pipetted to the wells. After incubation, the wells are again washed, followed by the addition of a TMB substrate solution to the wells. Color will develop in proportion to the amount of IL-13 Receptor alpha 2 bound in each well. Addition of the Stop Solution will change the color from blue to yellow, and the intensity of the color is measured at 450 nm.

  • Research areas

  • Function

    Binds as a monomer with high affinity to interleukin-13 (IL13), but not to interleukin-4 (IL4).
  • Sequence similarities

    Belongs to the type I cytokine receptor family. Type 5 subfamily.
    Contains 1 fibronectin type-III domain.
  • Domain

    The WSXWS motif appears to be necessary for proper protein folding and thereby efficient intracellular transport and cell-surface receptor binding.
    The box 1 motif is required for JAK interaction and/or activation.
