Fluorescein-dT phosphoramidite contains a DMT group to allow quantification of coupling. It can be inserted into a target sequence as a replacement for a dT residue. It provides a valuable tool to add the fluorescein tag to a desired location of an oligo sequence. It is complimentary to the commonly used 6-FAM phosphoramidite that contains no DMT group and can only be added at the 5'-terminus, thus terminating synthesis. AAT Bioquest also offer HEX-dT phosphoramidite, TET-dT phosphoramidite, biotin-dT phosphoramidite, biotin-dT CPG and Fluorescein-dT CPG.
