ASSAY FOR SERUM CHOLINESTERASE ACTIVITY, AND ANALYSTICAL ELEMENT

摘要

PURPOSE: To provide a dry analytical element for the determination of serum cholinesterase (CHE) activity in an undiluted aqueous body fluid. ;CONSTITUTION: The dry analytical element for the determination of serum cholinesterase (CHE) activity is disclosed. The element analyses an undiluted body fluid and employs butyrylthiocholine as the substrate for CHE. The bytyrylthiocholine is hydrolyzed by serum cholinesterase and liberates butyric acid and thiocholine. The thiocholine liberated then reduces ferricyanide to ferrocyanide and the rate of change is measured by reflectance densiometry.;COPYRIGHT: (C)1993,JPO
