Abstract

See full text

The present invention provides a process for increasing the quantum yield in the case of the oxidation of luminol or of a 7-dialkylaminonaphthalene-1,2-dicarboxylic acid hydrazide, each alkyl radical of which contains up to 3 carbon atoms, by a peroxide compound in the presence of peroxidase ( POD), wherein the reaction is carried out in the presence of fluorescein, the concentration of the fluorescein being in a concentration range which gives a quantum yield which is greater than the sum of the quantum yields of the individual chemiluminescing materials. The present invention also provides a reagent for the determination of POD, wherein it contains luminol or a 7-dialkylaminonaphthalene-1,2-dicarboxylic acid hydrazide, each alkyl radical of which contains up to 3 carbon atoms, fluorescein, a hydrogen peroxide provider, a buffer substance (pH 7.5 to 9) and optionally a sequestering agent.
