Description and Uses

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.
