The assay assesses cell viability by detecting the formazan product formed from the reduction of 3-(4,5-dimethylthiazole-2-yl)-2,5-biphenyl tetrazolium bromide (MTT) by mitochondrial succinate dehydrogenase of metabolically active cells [29].
We found that 46% of the seeds were viable using the Tetrazolium test.
The generally assessed study is cell viability with examples such as biomarkers for apoptosis, cell membrane integrity with lactase dehydrogenase (LDH) assay, comet assay for genotoxicity, immunohistochemistry, and tetrazolium reduction assays [48].

The culture was positive for pH 6 , it can utilize D-Glactouronic acid, L-Aspartic acid, D-Glucuronic acid, D-Serine and was found sensitive towards Troleandomycin, Lincomycin, Vancomycin, Rifamycin, Tetrazolium violet, Tetrazolium blue, 1% Sodium lactate, Potassium tellurite and 1% NaCl.
To analyze the type of muscle fibers, the reaction of nicotinamide adenine dinucleotide tetrazolium reductase (NADH-TR) was utilized, according to the model proposed by Camargo Filho et al., and used by and Castoldi et al.
The tetrazolium salt of WST-8 [2-(2-methoxy-4-nitrophenyl) -3-(4-nitrophenyl)-5-(2,4-disulfophenyl)-2H-tetrazolium, monosodium salt] was used as a metabolism indicator, as that salt penetrates into the viable cells, where it is metabolized in the mitochondria.
