Sandwich ELISA - Human IL-28A ELISA Kit (AB238269)

Interpolated concentrations of native IL28A in unstimulated and stimulated HUVEC cell culture supernatant samples.

HUVEC cells were stimulated by adding human IFN-a at 100 IU/mL for 20 hours, followed by the addition of Poly(I : C) at 30 μg/mL for 3 hours. The concentrations of IL28A were measured in duplicates, interpolated from the IL28A standard curves and corrected for sample dilution. Undiluted samples are as follows : unstimulated HUVEC cell supernatant 100% and stimulated HUVEC cell supernatant 100%. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). IL28A was not detectable in unstimulated HUVEC cell culture supernatant. The mean IL28A concentration was determined to be 545.5 pg/mL in stimulated HUVEC cell culture supernatant.

Product details

Human IL-28A ELISA Kit (ab238269) is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of IL-28A protein in cell culture supernatant. It uses our proprietary SimpleStep ELISA® technology. Quantitate Human IL-28A with 25.24 pg/ml sensitivity.

SimpleStep ELISA® technology employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details. Our SimpleStep ELISA® technology provides several benefits:

- Single-wash protocol reduces assay time to 90 minutes or less
- High sensitivity, specificity and reproducibility from superior antibodies
- Fully validated in biological samples
- 96-wells plate breakable into 12 x 8 wells strips

A 384-well SimpleStep ELISA® microplate (ab203359) is available to use as an alternative to the 96-well microplate provided with SimpleStep ELISA® kits.

Target data

Cytokine with antiviral, antitumour and immunomodulatory activities. Plays a critical role in the antiviral host defense, predominantly in the epithelial tissues. Acts as a ligand for the heterodimeric class II cytokine receptor composed of IL10RB and IFNLR1, and receptor engagement leads to the activation of the JAK/STAT signaling pathway resulting in the expression of IFN-stimulated genes (ISG), which mediate the antiviral state. Has a restricted receptor distribution and therefore restricted targets : is primarily active in epithelial cells and this cell type-selective action is because of the epithelial cell-specific expression of its receptor IFNLR1. Seems not to be essential for early virus-activated host defense in vaginal infection, but plays an important role in Toll-like receptor (TLR)-induced antiviral defense. Plays a significant role in the antiviral immune defense in the intestinal epithelium. Exerts an immunomodulatory effect by up-regulating MHC class I antigen expression.
