The NAD/NADH Quantification Kit provides a
convenient tool for sensitive detection of the
intracellular nucleotides, NAD and NADH, and their
ratio without the requirement to purify NAD/NADH from
samples. This assay is specific for NAD and NADH,
and does not detect NADP nor NADPH. NADtotal (NAD
and NADH) or NADH are quantified in a colorimetric
assay (450 nm).
