The Tat FRET Peptide has a flexible structure and shows efficient quenching of the dye when TAR RNA is absent. On binding to TAR RNA, a 2.6 fold fluorescence gain is observed as a result of conformational changes in the FRET peptide. TAR is a 59 nt RNA stem-loop structure that forms the 5'-end of all HIV-1 transcripts
