    摘要： The invention provides an ammonia elimination reagent in solution, comprising a thermo-resistant isocitrate dehydrogenase with prominent stability under conditions at high alkaline pHs. For example, the isocitrate dehydrogenase is preferably derived from the genus Thermus. For an assay system of biological substances generating a reaction product ammonia, an ammonia elimination reagent can be prepared by selecting and using the enzyme; the resulting ammonia elimination reagent can be stored in solution; additionally, the assay system can be designed in combination with both the coenzymes NAD+ and NADP+. The ammonia elimination reagent is novel and can eliminate ammonia in an extremely short time.
