The CoenzymeⅠ NAD(H) Content Assay Kit is widely used in biochemical and biomedical research to measure the levels of NAD+ and NADH in biological samples. It is essential for studying cellular metabolism, particularly in processes like glycolysis, the tricarboxylic acid (TCA) cycle, and oxidative phosphorylation. Researchers use this kit to investigate the redox state of cells, which is critical for understanding metabolic disorders, aging, and diseases such as cancer and diabetes. Additionally, it is employed in drug discovery and development to evaluate the efficacy of compounds targeting NAD+ metabolism. The kit provides a reliable and sensitive method for quantifying NAD+ and NADH, enabling insights into cellular energy balance and stress responses.
