Coenzyme derivatives and enzymes appropriate therefor

摘要

Highly stale derivatives of oxidized nicotinamide adenine dinucleotide (NAD), oxidized nicotinamide adenine dinucleotide phosphate (NADP), reduced nicotinamide adenine dinucleotide (NADH) and reduced nicotinamide adenine dinucleotide phosphate (NADPH); dehydrogenases which are highly reactive with these derivatives and show excellent stability; and an enzymological assay method and enzymological assay reagents by using the same. These reagents have high storage stability over a long time, i.e., at least 12 months (usually 13 months or longer) when stored at 10
