Used to measure oxidative DNA damage in biological samples such as urine, serum, plasma, and cell lysates. The kit detects 8-hydroxydeoxyguanosine, a biomarker formed when reactive oxygen species modify guanine in DNA. It is widely applied in studies related to aging, cancer, neurodegenerative diseases, diabetes, and environmental toxin exposure. Researchers use it to evaluate the effectiveness of antioxidants and assess overall oxidative stress levels in experimental models. The ELISA format allows for high-throughput, quantitative analysis with good sensitivity and specificity.
