      Intended use

      This ELISA kit applies to the in vitro quantitative determination of  8-OHdG concentrations in serum, plasma and other biological fluids.

      Test principle

      This ELISA kit uses the Competitive-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with 8-OHdG. During the reaction,  8-OHdG in the sample or standard competes with a fixed amount of 8-OHdG on the solid phase supporter for sites on the Biotinylated Detection Ab specific to  8-OHdG. Excess conjugate and unbound sample or standard are washed from the plate, and Avidin conjugated to Horseradish Peroxidase (HRP) are added to each microplate well and incubated. Then a TMB substrate solution is added to each well. The enzyme-substrate reaction is terminated by the addition of stop solution and the color change is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The concentration of  8-OHdG in the samples is then determined by comparing the OD of the samples to the standard curve.

      Assay type Competitive
      Format 96T
      Assay time 2.0h
      Reactivity Universal
      Detection Method Colormetric
      Detection Range 1.56—100 ng/mL
      Sensitivity 0.94 ng/mL
      Sample Volume 50μL
      Sample Type Serum, plasma and other biological fluids


      This kit recognizes 8-OHdG in samples. No significant cross-reactivity or interference between 8-OHdG and analogues was observed.

      Typical data

      As the OD values of the standard curve may vary according to the conditions of the actual assay performance (e.g. operator, pipetting technique, washing technique or temperature effects), the operator should establish a standard curve for each test. Typical standard curve and data is provided below for reference only.

      Intra-assay Precision (Precision within an assay): 3 samples with low, mid range and high level 8-OHdG were tested 20 times on one plate, respectively.
      Inter-assay Precision (Precision between assays): 3 samples with low, mid range and high level 8-OHdG were tested on 3 different plates, 20 replicates in each plate.

      The recovery of  8-OHdG spiked at three different levels in samples throughout the range of the assay was evaluated in various matrices.

      Sample Type Range (%) Average Recovery (%)
      Serum (n=5) 86-100 91
      EDTA plasma (n=5) 91-104 98
      Cell culture media (n=5) 93-106 98


      Samples were spiked with high concentrations of 8-OHdG and diluted with Reference Standard & Sample Diluent to produce samples with values within the range of the assay.
