SpecificityThis assay has high sensitivity and excellent specificity for detection of Anti-GAD. No significant cross-reactivity or interference between Anti-GAD and analogues was observed. NOTE: Limited by current skills and knowledge, it is impossible for us to complete the cross-reactivity detection between Anti-GAD and all the analogues, therefore, cross reaction may still exist in some cases.
Intended UseHuman GAD ELISA Kit allows for the in vitro quantitative determination of GAD , 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 specificalIntended Uses: This Anti-GAD ELISA kit is a 1.5 hour solid-phase ELISA designed for the quantitative determination of Human Anti-GAD. This ELISA kit for research use only, not for therapeutic or diagnostic applications!
Principle of the Assay: Anti-GAD LISA kit applies the competitive enzyme immunoassay technique utilizing Glutamic Acid Decarboxylase antigen and an Anti-GAD-HRP conjugate. The assay sample and buffer are incubated together with Anti-GAD-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 Anti-GAD concentration since Anti-GAD from samples and Anti-GAD-HRP conjugate compete for the Glutamic Acid Decarboxylase antigen binding site. Since the number of sites is limited, as more sites are occupied by Anti-GAD from the sample, fewer sites are left to bind Anti-GAD-HRP conjugate. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The Anti-GAD concentration in each sample is interpolated from this standard curve.
