title: Purification of reduced nicotinamide adenine dinucleotide by ion-exchange and high-performance liquid chromatography.
abstract: Combining ion-exchange (AG MP-1) and reversed-phase (C-18) partition chromatography accomplishes a higher degree of purification of NADH than either method can provide alone. Final elution in 95% ethanol, dehydration with anhydrous sodium sulfate, and storage in dry 1,2-propanediol over molecular sieves prevents hydrolysis of the purified dinucleotide.
