Rose Bengal（Cat No.:R024432）is a synthetic dye with a range of applications in medicine and research. Originally used as a diagnostic stain, it highlights damaged or degenerated cells, especially in eye exams to detect corneal and conjunctival abnormalities. Rose Bengal has also shown potential in photodynamic therapy, particularly in cancer treatment, where it generates reactive oxygen species upon light exposure to selectively target cancer cells. In microbiology, it is used as an indicator dye to differentiate bacterial species. Its versatility makes Rose Bengal valuable in diagnostic, therapeutic, and research applications.
