Cat. No.: HY-15924
CAS No.: 298-93-1
Synonyms: MTT; Thiazolyl Blue Tetrazolium bromide; Methylthiazolyldiphenyl-tetrazolium bromide
Thiazolyl Blue (MTT) is a cell-permeable and positively charged tetrazolium dye that is used to detect reductive metabolism in cells. Thiazolyl Blue is taken up by cells through the plasma membrane and then reduced to formazan by intracellular NAD (P) H-oxidoreductases. Thiazolyl Blue is frequently used in colorimetric assays to measure cell proliferation, cytotoxicity, and apoptosis .

Cat. No.: HY-D0714
CAS No.: 298-96-4
Synonyms: 2,3,5-Triphenyltetrazolium chloride; TPTZ; TTC
Tetrazolium Red (2,3,5-Triphenyltetrazolium chloride; TTC) is a not brain-penetrant, colorless, water-soluble dye that is reduced by mitochondrial enzymes to a deep red, water-insoluble compound (formazan) mainly in the mitochondria of living cells. Tetrazolium Red is used to observe the activity of dehydrogenase, and it turns colorless to red when exposed to hydrogen. Tetrazolium Red distinguishes between surviving and infarcted brain tissue after stroke. Tetrazolium Red has been used to stain heart tissue to measure the extent of acute lesions and also used to stain brain tissue to detect the size of the infarcted area. The absorption wavelength of Tetrazolium Red is 570 nm .

MTT Formazan is a purple water-insoluble product formed by the reduction of yellow soluble MTT by succinate dehydrogenase in the mitochondria of viable cells. The amount of MTT Formazan produced is proportional to cellular metabolic activity, and it can serve as an indicator for evaluating cell viability and proliferation. MTT Formazan exhibits solvent-dependent solubility properties, and its absorbance value can be measured by spectrophotometry to reflect cellular status. MTT Formazan also supports the assessment of cell viability in bacterial MTT assays. MTT Formazan can be used in photoacoustic microscopy to enhance the imaging effect of viable cells, especially in applications in the fields of three-dimensional cell culture and tissue engineering .

Cat. No.: HY-D0007
CAS No.: 1871-22-3
Synonyms: Tetrazolium blue
Blue Tetrazolium is a tetrazolium salt chromogenic dye that can be reduced to a dark blue formazan product. Blue Tetrazolium is applicable for assays such as succinate dehydrogenase activity detection and reducing sugar quantification. Blue Tetrazolium also serves as a novel corrosion inhibitor for cold-rolled steel in hydrochloric acid solutions. Blue Tetrazolium has a broad wavelength range (480-600 nm), with the maximum absorbance observed at 540 nm .
