TAMRA (tetramethylrhodamine) is a well known fluorophore that has a long history of use in biomolecule labeling. TAMRA can serve as a FRET acceptor for FAM (fluorescein).

TAMRA amine is a derivative having a primary amine group that can be conjugated with various electrophiles like activated esters, epoxides, etc., used in reductive amination reactions, and in enzymatic transamination.
