  • Product overview

    Human Caspase-1 ELISA Kit (ab219633) is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of Caspase-1 protein in tissue extracts, cell culture media, cell culture supernatant, and cell culture extracts. It uses our proprietary SimpleStep ELISA® technology. Quantitate Human Caspase-1 with 5.5 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.

  • Notes

    Caspase-1 is a thiol protease that cleaves IL-1 beta precursor releasing the mature cytokine which is involved in a variety of inflammatory processes. Caspase-1 is part of the inflammasome complex. It is important for defense against pathogens. Caspase-1 also cleaves and activates sterol regulatory element binding proteins (SREBPs). Caspase-1 can also promote apoptosis as it is part of caspase cascade.

    SimpleStep ELISA technology allows the formation of the antibody-antigen complex in one single step, reducing assay time to 90 minutes. Add samples or standards and antibody mix to wells all at once, incubate, wash, and add your final substrate. See protocol for a detailed step-by-step guide.

  • Interpolated concentrations of native Caspase-1 in human LPS treated (8 hours), mock treated (8 hours), and untreated THP-1 cell extract samples based on a 50 µg/mL extract load.
    Interpolated concentrations of native Caspase-1 in human LPS treated (8 hours), mock treated (8 hours), and untreated THP-1 cell extract samples based on a 50 µg/mL extract load.

    The concentrations of Caspase-1 were measured in duplicate and interpolated from the Caspase-1 standard curve and corrected for sample dilution. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean Caspase-1 concentration was determined to be 1497 pg/mL in LPS treated (8 hours) THP-1 cell extract, 1586 pg/mL in mock treated (8 hours) THP-1 cell extract, and 1735 pg/mL in untreated THP-1 cell extract.

    The concentrations of Caspase-1 were measured in duplicate and interpolated from the Caspase-1 standard curve and corrected for sample dilution. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean Caspase-1 concentration was determined to be 128.7 pg/mL in thyroid tissue extract and 2279 pg/mL in BxPC-3 cell extract.

  • Interpolated concentrations of native Caspase-1 in human cell culture supernatant samples.
    Interpolated concentrations of native Caspase-1 in human cell culture supernatant samples.

    Undiluted samples are as follows: THP-1 LPS neat, THP-1 mock neat, PBMC PHA-M neat, PBMC mock neat. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean Caspase-1 concentration was determined to be 549 pg/mL in LPS treated (8 hours) THP-1 cell culture supernatant, 41.8 pg/mL in mock treated (8 hours) THP-1 cell culture supernatant, 204 pg/mL PHA-M treated (2 days) PBMC cell culture supernatant, and 57.3 pg/mL in mock treated (2 days) PBMC cell culture supernatant.

    Human PBMC cells were cultured in the absence or presence of 1.5% PHA-M for 2 days. The concentrations of Caspase-1 were measured in three different dilutions of the supernatant samples in duplicates and interpolated from the Caspase-1 standard curve. The interpolated values are plotted (mean +/- SD, n=2). The mean Caspase-1 concentration was determined to be 549 pg/mL in LPS stimulated THP-1 cell supernatant, 41.8 pg/mL in unstimulated THP-1 cell supernatant, 204 pg/mL in PHA-M stimulated PBMC cell supernatant, 57.3 pg/mL in unstimulated PBMC supernatant, and undetectable in media (not shown).
