实验方案
在测定醇脱氢酶活性时，该测定使用β-烟酰胺腺嘌呤二核苷酸磷酸和在340nm处的连续分光光度法进行测定。
在测定透明质酸酶活性时，使用了一种在600 nm处的比浊测定法进行测定。在pH 5.35、37 °C下，一单位的透明质酸酶活性可每分钟引起0.330的吸光值改变。
To measure alcohol dehydrogenase activity, this assay uses β-nicotinamide adenine dinucleotide phosphate and a continuous spectrophotometric rate determination at 340 nm.
