2,3,5-Triphenyltetrazolium Chloride is a redox indicator. In the TTC assay (also known as TTC test or tetrazolium test), TTC is used to differentiate between metabolically active and inactive tissues. The white compound is enzymatically reduced to red TPF (1,3,5-triphenylformazan) in living tissues…

2,6-dichlorophenolindophenol (DCPIP) is a blue chemical compound used as a redox dye. In Oxidized form DCPIP is blue; whereas in reduced form DCPIP is colorless. The rate of photosynthesis can be measured by the rate at which this dye changes color (is reduced) when exposed to light in a…

Calcein is an indicator for the determination of calcium by titration with EDTA. The excitation wavelength and emission wavelength are 495/515 nm. It is suitable for fluorometric determination of calcium. It does not fluoresce in strong alkaline solution, but an intense fluorescence appears in the…

Sulforhodamine B is a fluorescent dye. Sulforhodamine B can be used as a protein tag - by sulfamido condensation with a proteinaceous substrate containing a primary amine function. Sulforhodamine B will fluoresce red. Because of its red fluorescence it can be used in conjuction with fluorescein…
