SpecificityThis assay has high sensitivity and excellent specificity for detection of 8OHDG. No significant cross-reactivity or interference between 8OHDG and analogues was observed. NOTE: Limited by current skills and knowledge, it is impossible for us to complete the cross-reactivity detection between 8OHDG and all the analogues, therefore, cross reaction may still exist in some cases.
Intended UseHuman 8-OHdG ELISA Kit allows for the in vitro quantitative determination of 8-OHdG , 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: 8OHDG ELISA kit applies the quantitative sandwich enzyme immunoassay technique. The microtiter plate has been pre-coated with a monoclonal antibody specific for 8OHDG. Standards or samples are then added to the microtiter plate wells and 8OHDG if present, will bind to the antibody pre-coated wells. In order to quantitatively determine the amount of 8OHDG present in the sample, a standardized preparation of horseradish peroxidase (HRP)-conjugated polyclonal antibody, specific for 8OHDG are added to each well to "sandwich" the 8OHDG immobilized on the plate. The microtiter plate undergoes incubation, and then the wells are thoroughly washed to remove all unbound components. Next, substrate solutions are added to each well. The enzyme (HRP) and substrate are allowed to react over a short incubation period. Only those wells that contain 8OHDG and enzyme-conjugated antibody will exhibit a change in color. The enzyme-substrate reaction is terminated by addition of a sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450 nm. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The 8OHDG concentration in each sample is interpolated from this standard curve.
