  • Product overview

    Mouse Legumain ELISA Kit (ab207617) is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of Legumain protein in cell culture extracts, cell culture supernatant, cit plasma, edta plasma, hep plasma, serum, and tissue extracts. It uses our proprietary SimpleStep ELISA® technology. Quantitate Mouse Legumain with NULL NULL 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

    Legumain is a lysosomal cysteine protease that plays a pivotal role in the endosomal/lysosomal degradation system. Specifically, Legumain is required for the normal degradation of internalized EGFR, allowing Legumain to regulate cell proliferation via this role. Mouse Legumain has 94% and 83% identity to rat and human Legumain, respectively.

    Legumain has a strong specificity for hydrolysis of asparaginyl bonds, but can also cleave aspartyl bonds slowly, especially under acidic conditions. Legumain deficiency causes the accumulation of pro-Cathepsins B, H and L, another group of lysosomal cysteine proteases. Overexpression of Legumain in tumors is significant for invasion/metastasis.

    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 Legumain in mouse serum and spiked Legumain in RPMI Base Media.

    The concentrations of Legumain were measured in duplicates, interpolated from the Legumain standard curves and corrected for sample dilution. Undiluted samples are as follows: serum 5%, and RPMI Base Media 10%. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean Legumain concentration was determined to be 9.1 ng/mL in serum and 1.7 ng/mL in RPMI Base Media 10%.

  • Interpolated concentrations of native Legumain in mouse plasma (heparin, EDTA, and citrate).
    Interpolated concentrations of native Legumain in mouse plasma (heparin, EDTA, and citrate).

    The concentrations of Legumain were measured in duplicates, interpolated from the Legumain standard curves and corrected for sample dilution. Undiluted samples are as follows: plasma (heparin) 5%, plasma (EDTA) 2.5% and plasma (citrate) 2.5%. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean Legumain concentration was determined to be 14.1 ng/mL in plasma (heparin), 7.7 ng/mL in plasma (EDTA) and 6.5 ng/mL in plasma (citrate).

    The concentrations of Legumain were measured in duplicate and interpolated from the Legumain standard curve and corrected for sample dilution. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean Legumain concentration was determined to be 2.77 ng/mL in mouse RAW 264.7 cell extract.
