Used for the quantitative measurement of human quinone oxidoreductase 1 (NQO1) levels in biological samples such as serum, plasma, and cell lysates. This ELISA kit is widely applied in research settings to study oxidative stress, cellular defense mechanisms, and the role of NQO1 in detoxification processes. It is particularly useful in cancer research, as NQO1 is overexpressed in many tumor types and is being investigated as a biomarker for tumor progression and response to therapy. The kit enables high-throughput analysis with high sensitivity and specificity, supporting studies in pharmacology, toxicology, and molecular biology related to antioxidant pathways and enzyme regulation.
