SpecificityThis assay has high sensitivity and excellent specificity for detection of GM2. No significant cross-reactivity or interference between GM2 and analogues was observed. NOTE: Limited by current skills and knowledge, it is impossible for us to complete the cross-reactivity detection between GM2 and all the analogues, therefore, cross reaction may still exist in some cases.
Intended UseHuman GM2AP ELISA Kit allows for the in vitro quantitative determination of GM2AP , 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: GM2 ELISA kit applies the competitive enzyme immunoassay technique utilizing a monoclonal anti-GM2 antibody and an GM2-HRP conjugate. The assay sample and buffer are incubated together with GM2-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 GM2 concentration since GM2 from samples and GM2-HRP conjugate compete for the anti-GM2 antibody binding site. Since the number of sites is limited, as more sites are occupied by GM2 from the sample, fewer sites are left to bind GM2-HRP conjugate. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The GM2 concentration in each sample is interpolated from this standard curve.
