SpecificityThis assay has high sensitivity and excellent specificity for detection of RPS21. No significant cross-reactivity or interference between RPS21 and analogues was observed. NOTE: Limited by current skills and knowledge, it is impossible for us to complete the cross-reactivity detection between RPS21 and all the analogues, therefore, cross reaction may still exist in some cases.
Intended UseHuman RPS21 ELISA Kit allows for the in vitro quantitative determination of RPS21 , concentrations in serum, Plasma , tissue homogenates and Cell culture supernates and Other biological fluids.

Product Description specificalPrinciple of the Assay: RPS21 ELISA kit applies the competitive enzyme immunoassay technique utilizing a polyclonal anti-RPS21 antibody and an RPS21-HRP conjugate. The assay sample and buffer are incubated together with RPS21-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 RPS21 concentration since RPS21 from samples and RPS21-HRP conjugate compete for the anti-RPS21 antibody binding site. Since the number of sites is limited, as more sites are occupied by RPS21 from the sample, fewer sites are left to bind RPS21-HRP conjugate. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The RPS21 concentration in each sample is interpolated from this standard curve.
