Product nameINT dye, tetrazolium dye precursor
DescriptionTetrazolium dye precursor used to measure dehydrogenase activity.
- 2-(4-Iodophenyl)-3-(4-nitrophenyl)-5-phenyl-2H-tetrazolium chloride
- Iodonitrotetrazolium chloride
Tetrazolium dye precursor that forms a purple formazan dye on reduction. Used as an electron acceptor for the colorimetric assay of dehydrogenase activity. Also used for western blot staining and as a staining agent for soft agar colony formation assays.
Chemical name2-(4-Iodophenyl)-3-(4-nitrophenyl)-5-phenyl-2H-tetrazolium chloride
Storage instructionsStore at -20°C. Store under desiccating conditions. The product can be stored for up to 12 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
