Human 8-OHdG ELISA kit is an accurate in vitro quantitative method for detecting 8-hydroxy-2-deoxyguanosine (8-OHdG, 8-OHdG check) in human saliva, serum, urine and plasma samples. This assay has a minimum sensitivity detection limit of 0.5 ng/ml.
8-hydroxy-2-deoxyguanosine (8-OHdG) is a modified base in the DNA as a result of an attack by hydroxyl radicals. These are formed has either intermediates or products during the process of oxidative stress or aerobic metabolism. There are many publications which support the involvement of free radical reactions in the DNA damage process of many biomolecules which can ultimately lead to many diseases in humans for example cancer, diabetes, neurodegenerative conditions (Alzheimer’s disease), rheumatoid arthritis, atherosclerosis, inflammation, cerebral and heart ischemia-reperfusion injury.
The measurement of 8-OHdG levels is becoming increasingly popular as a stable, sensitive and an integral marker for oxidative damage in cellular DNA. It can be excreted through urine and that its levels can be elevated if exposed to ionising radiation and tobacco smoke. It has been found that the concentration correlates well with the damage to DNA and oxidative stress that leads to the degenerative disease states.
All reagents supplied need to be stored at 2 °C – 8 °C, unopened reagents will retain reactivity until expiration date. Do not use reagents beyond this date.
