CAS 2869-83-2: Janus Green B

Janus green B is a fluorescent dye that forms reactive oxygen species in the presence of hydrogen peroxide. The dye has been used as a probe to monitor the energy metabolism of cells and can be used to measure enzyme activities. Janus green B is also used to determine how wastewater treatment processes work. This dye reacts with potassium dichromate, which produces heat, and titration calorimetry is then used to measure the amount of heat generated during this reaction. Optical sensors are then used to detect the fluorescence emitted by Janus green B.

Janus Green B

Janus Green B is a stain that interacts with DNA and has been used for histology studies including mitochondrial staining, in which its oxidation and reduction reveals alterations to the electron transfer chain. The stain has been utilized in studies for effective and rapid staining of insect chordotonal organs and peripheral nerves, where the nerves appear dark blue in comparison to non stained tissue. With the use of Janus Green B, rabbit lymphatic vessel studies demonstrate that threadlike structures within the lymphatic vessels, known as Bonghan ducts, contain a high density of mitochondria in their cells.
