Used in biochemical and biomedical research to measure NADPH levels in biological samples, this ELISA kit enables accurate quantification of NADPH concentration in cells and tissues. It is widely applied in studies related to cellular metabolism, oxidative stress, and antioxidant defense systems. Researchers use it to evaluate enzyme activities in metabolic pathways such as the pentose phosphate pathway and glutathione redox cycle. It is also valuable in investigating diseases involving redox imbalance, including diabetes, cancer, and neurodegenerative disorders. The assay supports high-throughput analysis and provides a sensitive and specific method for monitoring NADPH changes under experimental conditions.
