Used in research to measure oxidative DNA damage in biological samples. The kit detects 8-hydroxydeoxyguanosine, a biomarker formed when reactive oxygen species modify DNA. It is commonly applied in studies related to aging, cancer, neurodegenerative diseases, and environmental toxin exposure. The ELISA format allows for high-throughput quantification of 8-OHdG levels in urine, serum, plasma, and tissue extracts. Researchers use it to assess the effectiveness of antioxidants and to investigate the role of oxidative stress in disease mechanisms.
