HiLyte Fluor is the name for a family of fluorescent dyes produced by Anaspec.

They are a series of fluorescent labeling dyes that span the full visible spectrum. The full family includes acid, acid SE, amine, and C2 maleimide forms.

These dyes were developed as an alternative to Alexa (fluor) and Cy3 and Cy5 dyes. They are optimally paired with Qxl quenchers when used for FRET projects.
