Principle of the Assay: cTnI ELISA kit applies the competitive enzyme immunoassay technique utilizing a polyclonal anti-cTnI antibody and an cTnI-HRP conjugate. The assay sample and buffer are incubated together with cTnI-HRP conjugate in pre-coated plate for one hour. After the incubation period, the wells are decanted and washed five times. The wells are then incubated with a substrate for HRP enzyme. The product of the enzyme-substrate reaction forms a blue colored complex. Finally, a stop solution is added to stop the reaction, which will then turn the solution yellow. The intensity of color is measured spectrophotometrically at 450nm in a microplate reader. The intensity of the color is inversely proportional to the cTnI concentration since cTnI from samples and cTnI-HRP conjugate compete for the anti-cTnI antibody binding site. Since the number of sites is limited, as more sites are occupied by cTnI from the sample, fewer sites are left to bind cTnI-HRP conjugate. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The cTnI concentration in each sample is interpolated from this standard curve.

Intended Uses: This cTnI ELISA kit is a 1.5 hour solid-phase ELISA designed for the quantitative determination of Rat cTnI. This ELISA kit for research use only, not for therapeutic or test applications!

Small volumes of cTnI elisa kit vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.

MBS727624 is a ready-to-use microwell, strip plate ELISA (enzyme-linked immunosorbent assay) Kit for analyzing the presence of the Cardiac Troponin I (cTnI) ELISA Kit target analytes in biological samples. The concentration gradients of the kit standards or positive controls render a theoretical kit detection range in biological research samples containing cTnI. The ELISA analytical biochemical technique of the MBS727624 kit is based on cTnI antibody-cTnI antigen interactions (immunosorbency) and an HRP colorimetric detection system to detect cTnI antigen targets in samples. The ELISA Kit is designed to detect native, not recombinant, cTnI. Appropriate sample types may include undiluted body fluids and/or tissue homogenates, secretions. Quality control assays assessing reproducibility identified the intra-assay CV (%) and inter-assay CV(%).
