Product name CheKine™ Coenzyme Ⅰ NAD(H) Assay Kit
Applications notes Abbkine CheKine™ Coenzyme Ⅰ NAD(H) Assay Kitprovides a convenient tool for sensitive detection of the NAD and NADH, and their ratio in various tissues and subcellular organelles. This Kit is based on enzyme cycling reaction (It does not recognize NADP+/NADPH), in which the formed NADH reduces a formazan (MTT) reagent. The intensity of the reduced product color, measured at OD565 nm, is proportionate to the NAD+ /NADH concentration in the sample.

Additional Information

Background Nicotinamide adenine dinucleotide (NAD) is an enzymatic cofactor involved in many redox reactions. NAD functions as an electron carrier, cycling between the oxidized (NAD) and reduced (NADH) forms. In addition to its role in redox reactions, NAD plays critical roles in ADP-ribosylation reactions and as a substrate for sirtuins.
