Tetrazolium salts: a consumer's guide

The Histochemical Journal, 1976
The purities of seven tetrazolium salts, obtained from various commercial sources, have been assessed by thin layer chromatography, relative extinction coefficients, and melting points. MTT and INT were largely homogeneous on thin layer chromatography, although significant variations occurred in the melting point behaviour.

Reduction of tetrazolium salts by malarial parasites

Experimental Parasitology, 1968
Abstract Free and intraerythrocytic forms of Plasmodium berghei and P. knowlesi reduced tetrazolium salts to their colored formazans when these cells were incubated with TZ under anaerobic conditions. Mepacrine hydrochloride incubated with P. berghei in vitro inhibited tetrazolium reduction.

Radiolysis of solutions of tetrazolium salts

Russian Chemical Reviews, 1998
Published data on radiolysis of liquid (mainly aqueous, water–alcohol and alcoholic) and solid [mainly in poly(vinyl alcohol)] solutions of tetrazolium salts are generalised. The mechanism of radiolytic transformations of these compounds is discussed. Their application in dosimetry of ionising radiation is considered in detail.

Tetrazolium salts and formazans

2020
Tetrazolium salts discussed here are of the 2-H type, and contain one or more five-membered heterocyclic rings, each of which carries a delocalized positive charge. Such a tetrazolium compound may be represented by a pair of Kekule forms. Tetrazolium salts can be reduced to formazans by a variety of mild reductants, including those of enzyme-catalyzed ...

THE ENZYMATIC REDUCTION OF TETRAZOLIUM SALTS BY AMINES

Canadian Journal of Biochemistry and Physiology, 1956
An enzyme system effecting the dehydrogenation of amines has been detected in rat brain and liver suspensions by the use of tetrazolium dyes as terminal electron acceptors. Kinetic data on this system are presented and the evidence for requirement of a cofactor is described.

Reduction of Tetrazolium Salt

Nature, 1954
SOME two hundred papers dealing with the chemistry of triphenyltetrazolium chloride and its use as a redox-indicator have been reviewed by Ried1 and Smith2. In spite of its wide use in biology, up to the present little is known about its reducing mechanism, the influence of experimental conditions on it, on its redox-potential, etc., and therefore the ...

The reduction of tetrazolium salts by plant mitochondria

Histochemie, 1968
Data has been obtained concerning the reduction of tetrazolium salts by mitochondria isolated from Jerusalem artichoke tubers with succinate as the substrate using a direct recording spectrophotometric method of assay. ATP was found to increase the rate of reduction of the tetrazolium salts, this being independent of the effect ATP had on the rate of ...

Limitations of tetrazolium salts in delineating infarcted brain

Acta Neuropathologica, 1984
Tetrazolium salts, histochemical indicators of mitochondrial respiratory enzymes, have been used by some pathologists to detect infarcts in myocardium. We explored the utility of this technique in detecting experimental brain infarcts and report our findings.

Viability and Tetrazolium Salt in Ascites Tumours

Nature, 1960
THE use of tetrazolium salts in experimental and human pathology is valuable if the materials being examined are vital organs or tissues, for degenerating or dead tissue loses the ability to reduce tetrazolium salts1. The formation of formazan is widely used for the determination of general metabolism2.
