  • Product overview

    Dog CRP ELISA Kit (C-Reactive Protein) (ab256397) is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of CRP (C-Reactive Protein) protein in cell culture media, cit plasma, edta plasma, hep plasma, and serum. It uses our proprietary SimpleStep ELISA® technology. Quantitate Dog CRP (C-Reactive Protein) with 1.1 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.

  • Notes

    CRP (C-Reactive Protein) displays several functions associated with host defense: it promotes agglutination, bacterial capsular swelling, phagocytosis and complement fixation through its calcium-dependent binding to phosphorylcholine. CRP can interact with DNA and histones and it may scavenge nuclear material released from damaged circulations cells. CRP is secreted; it forms a homopentamer pentaxin (or pentraxin) which have a discoid arrangement of 5 non-covalently bound subunits. CRP binds 2 calcium ions per subunit. The concentration of CRP in plasma increases greatly during acute phase response to tissue injury, infection or other inflammatory stimuli. It is induced by IL1/interleukin-1 and IL6/interleukin-6.

    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.

    The CRP 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 CRP in dog serum and plasma samples.
    Interpolated concentrations of native CRP in dog serum and plasma samples.

    The concentrations of CRP were measured in duplicates, interpolated from the CRP standard curves and corrected for sample dilution. Undiluted samples are as follows: serum 50%, plasma (citrate) 50%, plasma (heparin) 50%, and plasma (EDTA) 25%. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean CRP concentration was determined to be 95.49 ng/mL in neat serum, 294.4 ng/mL in neat plasma (citrate), 44.19 ng/mL in neat plasma (heparin), and 1,113 ng/mL in neat plasma (EDTA).
