Tetrazolium Violet is an organic tetrazolium salt supplied as a chloride salt, containing tetrazolium violet as the active cation. It is a cell-permeable, positively charged dye that is reduced by metabolically active cells to form water-insoluble formazan, resulting in a visible color change. This property makes it useful for indicating cellular metabolic activity and redox potential.
The dye is reactive to intracellular reduction processes and is widely applied in microbiology, biochemistry, and cell biology research. It has also been reported to show antineoplastic and apoptosis-inducing properties which support its use in biomedical research.Â

Tetrazolium Violet is a cell-permeable tetrazolium salt that functions as a redox-sensitive dye. It is reduced by metabolically active cells to form an insoluble colored formazan.
Tetrazolium Violet is used for microbial metabolism studies, redox activity assays, cell staining, alkaline phosphatase detection in immunoblots, and bacteriophage plaque assays.
Tetrazolium Violet enters living cells and is reduced by cellular metabolic activity to produce water-insoluble formazan. The resulting color change serves as an indicator of cellular respiration and redox activity.
Tetrazolium Violet is a sensitive indicator of cellular metabolism and redox activity and is useful for microbiological, biochemical, immunological, and cell biology research.
