Biological Activity: Erythrosine B (Erythrosin extra bluish; Tetraiodofluorescein) is a visible red dye and insecticide with colorimetric and fluorescent properties. Erythrosine B serves as a membrane-impermeant live-cell dye for Gram-positive and Gram-negative bacteria, primarily staining dead cells with damaged plasma membranes. Erythrosine B exhibits photosensitive larvicidal toxicity against Culex pipiens quinquefasciatus larvae. Erythrosine B is used in live/dead bacterial assays in colorimetric and fluorescent measurements for low-, medium-, and high-throughput experiments, as well as in research related to mosquito-borne diseases and food coloring[1][2][3][4].
