  • 製品の概要

    Human LECT2 ELISA Kit (ab269554) is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of LECT2 protein in hep plasma, serum, cit plasma, tissue extracts, and edta plasma. It uses our proprietary SimpleStep ELISA® technology. Quantitate Human LECT2 with 0.706 ng/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.

  • 特記事項

    Leukocyte cell derived chemotaxin 2 (LECT2) is a highly conserved protein that functions with major development in liver regeneration, immune modulation, bone growth, neuronal development, cancer, and several more in pathophysiology. Studies have shown LECT2 to be a positive regulator of chondrocyte proliferation. Moreover, the liver is considered to be the source of LECT2 due to exceptionally high levels of mRNA. However, expression in these cells is extremely low or undetectable suggesting that hepatocytes secrete LECT2 instantly after production.

    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.

  • Example of human LECT2 standard curve in Sample Diluent NS.
    Example of human LECT2 standard curve in Sample Diluent NS.

    The LECT2 standard curve was prepared as described in Section 10. Raw data values are shown in the table. Background-subtracted data values (mean +/- SD) are graphed.

  • Interpolated concentrations of native LECT2 in human serum and plasma samples.
    Interpolated concentrations of native LECT2 in human serum and plasma samples.

    The concentrations of LECT2 were measured in duplicates, interpolated from the LECT2 standard curves and corrected for sample dilution. Undiluted samples are as follows: serum 25%, plasma-citrate 25%, plasma-EDTA 25%, and plasma-heparin 25%.  The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean LECT2 concentration was determined to be 28.4 ng/mL in serum, 22.5 ng/mL in plasma-citrate, 32.5 ng/mL in plasma-EDTA, and 13.0 ng/mL in plasma-heparin.

  • Serum from ten individual healthy human female donors were measured in duplicate.
    Serum from ten individual healthy human female donors were measured in duplicate.

    Interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean LECT2 concentration was determined to be 51 ng/mL with a range of 20 - 125 ng/mL.

  • Interpolated concentrations of native LECT2 in human lung extract based on a 1,000 µg/mL extract load.
    Interpolated concentrations of native LECT2 in human lung extract based on a 1,000 µg/mL extract load.

    The concentrations of LECT2 were measured in duplicate and interpolated from the LECT2 standard curve and corrected for sample dilution. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean LECT2 concentration was determined to be 8.8 ng/mL in lung extract.
