  • 製品の概要

    Human TIMP2 ELISA Kit (ab270213) is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of TIMP2 protein in cell culture supernatant, edta plasma, saliva, serum, urine, cit plasma, hep plasma, and cell culture media. It uses our proprietary SimpleStep ELISA® technology. Quantitate Human TIMP2 with 19.5 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.

  • 特記事項

    TIMP2 (tissue inhibitor of metalloproteinases 2) is a member of the TIMP gene family that are known to be natural inhibitors of the matrix metalloproteinases. Moreover, TIMP2 has a unique function in its ability to suppress the proliferation of endothelial cells in response to angiogenic factors as well as inhibiting protease activity in tissues undergoing extracellular matrix remodeling. As a result, making TIMP2 critical to the maintenance of tissue homeostasis.

      Example of human TIMP2 standard curve in Sample Diluent NS.

      The TIMP2 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 TIMP2 in human serum and plasma samples.
      Interpolated concentrations of native TIMP2 in human serum and plasma samples.

      The concentrations of TIMP2 were measured in duplicates, interpolated from the TIMP2 standard curves and corrected for sample dilution. Undiluted samples are as follows: serum 15%, plasma (citrate) 15%, plasma (EDTA) 15%, and plasma (heparin) 10%. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean TIMP2 concentration was determined to be 25,723 pg/mL in serum, 30,263 pg/mL in plasma (citrate), 22,927 pg/mL in plasma (EDTA), and 17,596 pg/mL in plasma (heparin).

      Interpolated concentrations of native TIMP2 in human urine and saliva samples.

      The concentrations of TIMP2 were measured in duplicates, interpolated from the TIMP2 standard curves and corrected for sample dilution. Undiluted samples are as follows: urine 100%, saliva 12.5%, HepG2 supernatant 10%. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean TIMP2 concentration was determined to be 3,088 pg/mL in urine, 5,618 pg/mL in saliva, and 8,400 pg/mL in HepG2 supernatant.
