SpecificityThis assay has high sensitivity and excellent specificity for detection of ?2-GP1 AB IGA. No significant cross-reactivity or interference between ?2-GP1 AB IGA and analogues was observed. NOTE: Limited by current skills and knowledge, it is impossible for us to complete the cross-reactivity detection between ?2-GP1 AB IGA and all the analogues, therefore, cross reaction may still exist in some cases.
Intended UseHuman beta2 GP1 Ab IgA ELISA Kit allows for the in vitro quantitative determination of beta2 GP1 Ab IgA , 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: ?2-GP1 AB IGA ELISA kit applies the competitive enzyme immunoassay technique utilizing a monoclonal anti-?2-GP1 AB IGA antibody and an ?2-GP1 AB IGA-HRP conjugate. The assay sample and buffer are incubated together with ?2-GP1 AB IGA-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 ?2-GP1 AB IGA concentration since ?2-GP1 AB IGA from samples and ?2-GP1 AB IGA-HRP conjugate compete for the anti-?2-GP1 AB IGA antibody binding site. Since the number of sites is limited, as more sites are occupied by ?2-GP1 AB IGA from the sample, fewer sites are left to bind ?2-GP1 AB IGA-HRP conjugate. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The ?2-GP1 AB IGA concentration in each sample is interpolated from this standard curve.
