Additional Information

Assay Principle


Bring all reagents of the  to room temperature before beginning 8-hydroxy-2′-deoxy-guanosine (8-OHdG) Ultrasensitive ELISA assay kit.  Determine the number of microwells needed for the assay (each sample, standard, and control should be assayed in duplicate).  Bring all reagents and samples to room temperature (20-­25ºC) before use.

Assay Procedure


  1. Reconstitute the primary antibody with the primary antibody solution. Allow dissolving completely.
  2. Add 50µl of sample or standard per well.
  3. Add 50µl of reconstituted primary antibody per well. Shake the plate from side to side and mix fully. Cover plate with adhesive strip, making sure it is sealed tightly. Incubate at 4C for overnight.
  4. Pour off contents of plate into sink. Pipette 250µl washing solution into each well. After washing thoroughly by shaking the plate from side to side, dispose of washing solution. Invert plate and blot against clean paper towel to remove any remaining washing buffer. Repeat wash two times more.
  5. Reconstitute the secondary antibody with the secondary antibody solution. Allow dissolving completely.
  6. Add 100µl of constituted secondary antibody per well. Shake the plate from side to side and mix fully.
  7. Cover the plate with an adhesive strip. Incubate room temperature for 1 hour.
  8. At the end of the incubation period, repeat wash as in step 4.
  9. Reconstitute the chromatic solution (enzyme substrate solution) with 100 times volume of the diluting solution. Add 100µl of the reconstituted enzyme substrate per well. Shake the plate from side to side and mix fully. Incubate at room temperature for 15 minutes. This incubation should be done in the dark, i.e. shield the plate with aluminum foil.
  10. Add 100µl of the reaction terminating solution. Shake the plate from side to side and mix fully.
    After terminating the reaction, read the absorbance at 450 nm.
  11. Use a standard curve to determine the amount of 8-OHdG present in test samples. Generate the standard curve by plotting absorbance vs. log (concentration of standards). Then use the absorbance values obtained for the test samples to determine the concentrations.
