Eosin B

Catalog No.: A25012
Dye
Eosin B (Acid Red 91) is a multifunctional dye that primarily serves as a vital tool in biological research. Its primary mechanism involves staining biological samples, enabling the visualization and analysis of cell structures, tracking of biomolecules, and evaluation of cell functions. Eosin B is instrumental in distinguishing cell types, detecting biomolecules, studying tissue pathology, and monitoring microorganisms, making it suitable for diverse applications in both fundamental scientific research and clinical diagnostics. Additionally, it finds utility in traditional textile dyeing and emerging areas such as food pigments and dye-sensitized solar cells.
