5'-hexachlorofluorescein phosphoramidite
there are several ways of labeling an oligonucleotide with fluorescein. the choice of label is diversified further, depending on the spectral requirements. 5’-fluorescein-ce phosphoramidite, derived from the single isomer 6-carboxyfluorescein, 5’-hexachlorofluorescein-ce phosphoramidite (hex) and 5’-tetrachlorofluorescein-ce phosphoramidite (tet) can all be used to efficiently label an oligonucleotide at the 5’-end. labeling the 3’-end of an oligo with fluorescein can be achieved using 3’-fluorescein cpgs. standard cleavage and deprotection with ammonium hydroxide liberates the fluorescein-labeled oligo when using any of these supports.
