2,3,5 Triphenyl tetrazolium Chloride CAS 298-96-4
Usage: Chromogenic substrate for dehydrogenase
Tetrazolium Red is used to visualise dehydrogenase enzyme activity. Initially the tetrazolium solution is colorless but changes to red when it comes into contact with hydrogen. Tetrazolium red is used in a biochemical viability test for seeds. The test relies on dehydrogenase enzymes to release hydrogen ions which subsequently reduce the colorless tetrazolium salt solution to a red compound called formazan. Living cells turn red, while dead cells remain colorless.

Nuclear Fast Red Ammonium Salt (C.I.60760) CAS 84100-72-1
Nuclear fast red (CI 60760), also known as Kernechtrot, is commonly used in conjunction with an excess of aluminum ions as a red nuclear counterstain following histochemical procedures that yield blue products. The dye has also been used as a histochemical and colorimetric reagent for calcium.
