FormPowder
Erythrosin B, also called Acid Red 51, is used as a food colorant, in printing inks and as a biological stain in plant anatomy. It finds application as a dental plaque disclosing agent and a sensitizer for orthochromatic photographic films. As a food additive, it is commonly used in sweets like candies, popsicles and in cake-decorating gels. It is an important dye used in the determination of cell viability and used as phosphorescent triplet probe to detect rotational diffusion of membrane proteins.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
