Product Description specificalIntended Uses: This chondroitin epitopes 7d4 ELISA kit is a 1.5 hour solid-phase ELISA designed for the quantitative determination of Human chondroitin epitopes 7d4. This ELISA kit for research use only, not for therapeutic or diagnostic applications!
Principle of the Assay: chondroitin epitopes 7d4 ELISA kit applies the competitive enzyme immunoassay technique utilizing a monoclonal anti-chondroitin epitopes 7d4 antibody and an chondroitin epitopes 7d4-HRP conjugate. The assay sample and buffer are incubated together with chondroitin epitopes 7d4-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 chondroitin epitopes 7d4 concentration since chondroitin epitopes 7d4 from samples and chondroitin epitopes 7d4-HRP conjugate compete for the anti-chondroitin epitopes 7d4 antibody binding site. Since the number of sites is limited, as more sites are occupied by chondroitin epitopes 7d4 from the sample, fewer sites are left to bind chondroitin epitopes 7d4-HRP conjugate. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The chondroitin epitopes 7d4 concentration in each sample is interpolated from this standard curve.
