Product overview
Human IL-20 ELISA Kit (ab231927) is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of IL-20 protein in cit plasma, edta plasma, hep plasma, and serum. It uses our proprietary SimpleStep ELISA® technology. Quantitate Human IL-20 with 4.2 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.

Example of human IL-20 standard curveBackground-subtracted data values (mean +/- SD) are graphed.
-
Interpolated concentrations of spiked IL-20 in human serum and plasma samplesThe concentrations of IL-20 were measured in duplicates, interpolated from the IL-20 standard curves and corrected for sample dilution. Undiluted samples are as follows: serum 50%, plasma (EDTA) 50%, plasma (heparin) 50% and plasma (citrate) 50%. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2).
Serum from ten individual healthy human female donors were measured in duplicate. Interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). No detectable levels of IL-20 were measured.
-
Interpolated concentrations of spiked IL-20 in human cell culture media sampleThe concentrations of IL-20 were measured in duplicates, interpolated from the IL-20 standard curves and corrected for sample dilution. Undiluted samples are as follows: media 50%. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2).
