uniprot entry name :
ESR1_HUMAN
specificity :
This 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.
storage stability :
Store all reagents at 2-8 degree C.

products description :
Princple 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.
