  • Product overview

    Abcam’s IL-28A (Interleukin 28A) Human ELISA (Enzyme-Linked Immunosorbent Assay) kit is an in vitro enzyme-linked immunosorbent assay for the quantitative measurement of Human IL-28A in serum, plasma, and cell culture supernatants.

    This assay employs an antibody specific for Human IL-28A coated on a 96-well plate. Standards and samples are pipetted into the wells and IL-28A present in a sample is bound to the wells by the immobilized antibody. The wells are washed and biotinylated anti-Human IL-28A 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-28A bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.

  • Tested applicationsSuitable for: Sandwich ELISAmore details
  • PlatformMicroplate


  • FunctionCytokine with immunomodulatory activity. Up-regulates MHC class I antigen expression. Displays potent antiviral activity. Also displays antitumor activity. Ligand for the heterodimeric class II cytokine receptor composed of IL10RB and IL28RA. The ligand/receptor complex seems to signal through the Jak-STAT pathway.
  • Sequence similaritiesBelongs to the IL-28/IL-29 family.
  • Cellular localizationSecreted.

Unfortunately, we do not have any cross reactivity data with ab100567 and IL-28B. Since human IL-28A does have very high homology with human IL-28B (96%) it is possible that the antibody pair in the kit is also detecting IL-28B. However, without data t...

Thank you for your patience.

Unfortunately, it looks like that neither the cross-reactivity has been determined, nor the epitope for this antibody mapped. However, as the two protein are up to 95% identical, it is very likely that the antibody...

Thank you for your inquiry.

Unfortunately, epitope mapping has not been performed for the antibodies used in the ab100567, nor has IL-28B been tested with this kit so the cross reactivity with IL-28B is not known. Therefore this information w...
