A suitable tetrazolium salt is added and a frozen section of the sample is prepared.
A preferred tetrazolium salt is 2-(2'-benzothiazolyl)-5-styryl-3-(4'-phthalhydrazidyl)-tetrazolium chloride reduced in the presence of 1-methoxy-phenazinium methosulphate.
A steam-sensitive ink comprises, as active ingredient, a tetrazolium salt.
The reagent includes an enzyme, a phenazine derivative, a tetrazolium salt, and a divalent metal salt to stabilize the reagent.
Preferably the acylation is an acetylation and the further compound is a tetrazolium salt which is reduced to a formazan.
The mitochondrial activity of the cells is reflected by the conversion of the tetrazolium salt MTT into formazan crystals, which can be solubilized for homogenous measurement.
The invention relates to a kit for measuring the amount of analyte in a sample, comprising a tablet comprising a tetrazolium salt, diaphorase and NAD+, and at least one enzyme active on the analyte to be measured is described.
