1.Maikaʻi ka wai hoʻonā
2.Good kūpaʻa.

ʻO β-NAD + he coenzyme o dehydrogenase, a loaʻa iā β-NAD + ka hydrogen i ka wā o ka hopena a hoʻemi iā ia iho i NADH.Ma ke ʻano he hōʻailona a me ka substrate chromogen, loaʻa i ka NADH kahi kiʻekiʻe absorption ma 340 nm, hiki ke hoʻohana ʻia no ka ʻike.
No ka hoʻomākaukau ʻana i nā reagents noiʻi ʻepekema.Me ka NADH e like me ka mea hōʻailona a me ka chromogen substrate, aia kahi absorption peak ma 340 nm, hiki ke hoʻohana ʻia no ka ʻike ʻana i ka lactate dehydrogenase, transaminase a pēlā aku.
