SpecificityThis assay has high sensitivity and excellent specificity for detection of GSEC. No significant cross-reactivity or interference between GSEC and analogues was observed. NOTE: Limited by current skills and knowledge, it is impossible for us to complete the cross-reactivity detection between GSEC and all the analogues, therefore, cross reaction may still exist in some cases.
Intended UseMouse Gamma secretase ELISA Kit allows for the in vitro quantitative determination of Gamma secretase , concentrations in serum, Plasma , tissue homogenates and Cell culture supernates and Other biological fluids.
StorageFor 5-7days:Store the whole kit at 4℃
For a Long time :Store the Substrate at 4℃, other reagent should store at -20℃.
Product Description specificalPrinciple of the assay: GSEC ELISA kit applies the competitive enzyme immunoassay technique utilizing a monoclonal anti-GSEC antibody and an GSEC-HRP conjugate. The assay sample and buffer are incubated together with GSEC-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 GSEC concentration since GSEC from samples and GSEC-HRP conjugate compete for the anti-GSEC antibody binding site. Since the number of sites is limited, as more sites are occupied by GSEC from the sample, fewer sites are left to bind GSEC-HRP conjugate. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The GSEC concentration in each sample is interpolated from this standard curve.
