MTT MTT, 3-(4,5-Dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide [CAS: 2348-71-2]
Item #: M009 -

Reaction Scheme Product DescriptionMTT is slightly soluble in methanol, but has very low solubility in ethanol. It barely dissolves in ether, acetone, or ethyl acetate. MTT is utilized for cell viability detection. Since MTT has a positive charge, it can pass through a cell membrane and is reduced by mitochondria to form a purple color formazan dye. Organic solvent is requried to dissovle MTT formazan dyes. ...

Nitro-TB Nitro-TB, 3,3-[3,3’-Dimethoxy-(1,1’-biphenyl)-4,4’-diyl]-bis[2-(4-nitrophenyl)-5-phenyl-2H-tetrazolium chloride] [CAS: 298-83-9]
Item #: N011 -

Reaction Scheme Product Description Nitro-TB is dissolved by hot water or hot methanol. Other organic solvents such as acetone and ether cannot solubilize Nitro-TB. Nitro-TB is easily reduced by dehydrogenase to purple formazan dye aggregates. It is used for dehydrogenase detection on agarose gels. ...

TB TB, 3,3-[3,3’-Dimethoxy-(1,1’-biphenyl)-4,4’-diyl]-bis(2,5-diphenyl-2H-tetrazolium chloride) [CAS: 1871-22-3]
Item #: T012 -

Reaction Scheme Product Description TB is slightly soluble in water, but does not dissolve easily in acetone, ethyl acetate, and ether. Other organic solvents such as methanol, ethanol, and tetrachloromethane can solubilize TB pretty well. Since TB is easily reduced with dehydrogenase to generate reddish-purple formazan dye aggregates, it is used for dehydrogenase detection in tissue samples. ...

WST-1 WST-1, 2-(4-Iodophenyl)-3-(4-nitrophenyl)-5-(2,4-disulfophenyl)-2H-tetrazolium, monosodium salt [CAS: 150849-52-8]
Item #: W201 -

Oxidation Reaction Product Description of WSTs Water-soluble tetrazolium salts (WSTs) were developed by introducing positive or negative charges and hydroxy groups to the phenyl ring of the tetrazolium salt. Positive charges, such as trialkylammonio groups, improve the water-solubility of the formazan dye. However, a large cation is easily precipitated out with organic anions such as carboxylate or phosphate. Although a hydroxy group also improved the water solubility of the tetrazolium salt,...

WST-3 WST-3, 2-(4-Iodophenyl)-3-(2,4-dinitrophenyl)-5-(2,4-disulfophenyl)-2H-tetrazolium, monosodium salt
