Description

Erythrosin B is a fluorescent dye that is used in biological research. It has been shown to have cytotoxic effects on human leukemia cells (HL-60) and cytotoxic effects on human lymphocytes. The toxicities of this compound are dependent on the concentration and the duration of exposure, as well as the type of biological sample. Erythrosin B can be used to detect DNA damage in cells by using an analytical method called matrix effect synchronous fluorescence. This dye appears to be genotoxic in vitro and in vivo, but its long-term toxicity is unknown. Erythrosin B has antimicrobial properties against gram-positive bacteria and fungi, but it does not have any activity against Gram negative bacteria or viruses.
