Do you offer FITC labeled primers?

IDT offers a 6-FAM fluorophore modification instead of the traditional FITC fluorophore modification. FITC and FAM are both derivatives of fluorescein. FITC is fluorescein with an isothiocyanate reactive group added, while 6-FAM is 6-carboxyfluorescein. FITC and 6-FAM have identical spectral characteristics. In experiments, 6-FAM performs exactly like FITC. Read more about IDT fluorescein modifications and fluorescence applications.
