Beschreibung

Anwendung

Janus Green B has been used in staining technique to determine cell density, to detect the presence of telocytes in trachea and lungs and used as a dye to visualize bonghan ducts inside lymphatic vessels of rabbits.

Biochem./physiol. Wirkung

Janus Green B belongs to the phenazine group of dyes. It is a dark green/dark brown/dark black powder. Janus Green B should be oxidized to become colored. Thus, this dye can be used to specifically stain mitochondria in living cells. It has been used to stain biomolecules, nucleic acids and chromosomes. In addition, it is also used to stain various living organisms including fungi, yeast cell, brain, spinal cord, sperms and tissue culture monolayer. Janus Green B acts as an antimalarial agent. It also facilitates diagnostic assays and diagnosis of disease related to amyloid accumulation.
