SpecificityThis assay has high sensitivity and excellent specificity for detection of CoL2-Ab. No significant cross-reactivity or interference between CoL2-Ab and analogues was observed. NOTE: Limited by current skills and knowledge, it is impossible for us to complete the cross-reactivity detection between CoL2-Ab and all the analogues, therefore, cross reaction may still exist in some cases.

Product Description
specificalPrinciple of the assay: CoL2-Ab ELISA kit applies the competitive enzyme immunoassay technique utilizing collagen type 2 antigen and an CoL2-Ab-HRP conjugate. The assay sample and buffer are incubated together with CoL2-Ab-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 CoL2-Ab concentration since CoL2-Ab from samples and CoL2-Ab-HRP conjugate compete for the collagen type 2 antigen binding site. Since the number of sites is limited, as more sites are occupied by CoL2-Ab from the sample, fewer sites are left to bind CoL2-Ab-HRP conjugate. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The CoL2-Ab concentration in each sample is interpolated from this standard curve.
