Used in oxidative stress research to measure DNA damage in biological samples. The kit enables quantification of 8-hydroxydeoxyguanosine, a biomarker formed when reactive oxygen species modify DNA. It is widely applied in studies related to aging, neurodegenerative diseases, cancer, and environmental toxin exposure. The ELISA format allows high-throughput, sensitive detection in urine, serum, plasma, and tissue extracts. Commonly used in preclinical studies and biomonitoring to assess cellular oxidative damage and evaluate antioxidant therapies.
