Application 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 away, and Avidin-Horseradish Peroxidase (HRP) conjugate are added to each micro plate 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 turns from blue to yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The concentration of 8-OHdG in tested samples can be calculated by comparing the OD of the samples to the standard curve.

Asked: Is this kit useful for urine samples from rats?



adminSubmitted [ May 24 2021 ]

Answered: E-EL-0028 is suitable for the detection of rat urine samples. We have validated this kit with healthy rat urine, all the samples were undiluted and the reference value was about 2-12 ng/mL.
