实验方案
在测定5′-核苷酸酶活性时，本操作流程使用5′-单磷酸腺苷和一种显色试剂生成的标准曲线而对释放的磷的微摩尔数进行测定。
To measure 5′-nucleotidase activity, this procedure uses adenosine 5’-monophosphate and a color reagent to create a standard curve for determining the micromoles of phosphorus liberated.
Derived from procedure SSPHYT02. Includes template updates to current SOP specifications and incorporation of notes into the procedure.
