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

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