  • 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 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.

    We have not been able to detect endogenous Human IL-28A in normal serum with ab100567, only in serum spiked with Human IL-28A.

    Optimization may be required with urine samples.

  • Tested applications
    Suitable for: Sandwich ELISAmore details
  • Platform


  • Function
    Cytokine 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 similarities
    Belongs to the IL-28/IL-29 family.

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...
