Bio-assay based on enzymatic hydrogen peroxide colour reaction

摘要

Determn. of an analyte in a biological fluid comprises reacting the analyte with an H2O2-forming oxidase and detecting the resulting H2O2 by a peroxidase-dependent colour reaction. The reagent soln. contains /-0.1 mM K4Fe(CN)6 (I). Also claimed is a reagent for the analysis with /-0.1 mM K4Fe(CN)6 in the test soln..
