Acid Red 87, also known as Eosin Y, used as an acidic red stain for cell cytoplasm and as a background stain, thereby giving contrast to the nuclear stains. In histopathology, it is applied as a counterstain after hematoxylin and before methylene blue. Acid Red 87 is also a dye photosensitizer that catalyzes electron-transfer reaction for efficient regeneration of NADH through a photosensitizer-electron relay dyad. Recently was shown that the combination of eosin Y with light-emitting diode produced bacterial inactivation, being a potential candidate for photodynamic inactivation.

Sample Use Guides
Bacteria (107 CFU per ml) were incubated with eosin Y (ACID RED 87) at concentrations ranging from 0·1 to 10 μmol l-1 , irradiated by green LED (λmax 490-570 nm) for 5, 10 and 15 min and the cellular viability was determined. Pseudomonas aeruginosa was completely inactivated when treated with 10 μmol l-1 eosin Y for 10 min.
