FAM-dT phosphoramidite allows fluorescein (FAM) to be introduced into any position in the oligonucleotide sequence during synthesis by the phosphoramidite method (in the middle of the chain, at the 5’- and 3’-terminus). The reagent is a conjugate of deoxythymidine phosphoramidite and 6-isomer of FAM. Modification is performed during oligonucleotide synthesis by substituting standard dT phosphoramidite with fluorescein-dT phosphoramidite. This modification does not affect exonuclease or polymerase activity.
