Nicotinamide adenine dinucleotide (NAD(+)) plays a critical role in regulating numerous biological and physiological pathways including metabolism, inflammation, cancer, and aging in mammals. Here we describe a highly quantitative method with reverse-phase high-performance liquid chromatography (HPLC) for the determination of NAD(+) levels in cells and tissues. This methodology provides accurate, reliable, and reproducible results of NAD(+) measurement, which enables us to analyze various pathophysiological changes in NAD(+) levels in vitro and in vivo.
烟酰胺腺嘌呤二核苷酸(NAD(+))在调节包括哺乳动物的代谢、炎症、癌症和衰老等众多生物学和生理途径中起着关键作用。在此,我们描述了一种采用反相高效液相色谱法(HPLC)测定细胞和组织中NAD(+)水平的高度定量方法。该方法提供了准确、可靠且可重复的NAD(+)测量结果,使我们能够在体外和体内分析NAD(+)水平的各种病理生理变化。
