Highly stable oxidative coupling dye for spectrophotometric determination of analytes

摘要

A dye coupled compound is provided for use in a test device containing a reagent system for detecting the presence or quantity of an analyte in a sample. The reagent system comprises one or more enzymes which, in the presence of the analyte, produce an oxidising agent in quantities indicative of the quantity of analyte in the sample. The compound of choice is metaÄ3-methyl 2-benzothiazolinonehydrozoneÜN-sulfonyl benzenesulfonate monosodium.
