Erythrosine B (free acid)
Erythrosine B free acid is a visibly red dye with colorimetric and fluorescent properties that serves as an important dye for many Gram-positive and -negative bacteria. Erythrosine B free acid can be used for live/dead determination in both colorimetric and fluorescence-based assays for low, medium and high-throughput experimentation[1].
