Fluorescent Dyes

Fluorescent dyes can be used in a variety of staining and biological labeling applications. The dyes will emit in the ultraviolet, visible or near infrared. The dyes are listed based on the solvent tested in, altering the solvent can alter the color of the dye. See the dyes below and click to see samples of their color in different solvents.
