Superior fluorescent labeling dyes

  1. iFluor™ dyes and Alexa Fluor® dyes and other labeling dyes, courmainsfluoresceinsrhodamines, and cyanines are the most common fluorephores.
  2. FITC (fluorescein isothiocyanate), a fluorescein derivative is one of the most popular fluorescent labeling dyes, and predominantly used for preparing a variety of fluorescent bioconjugates.
  3. FAM, TAMRA, Texas Red®, Cy3®, Cy5® and Cy7® are also popular classic fluorescent labeling dyes used for preparing peptide and oligonucleotide conjugates.
