6-TAMRA-SE  (Synonyms: 6-TAMRA-NHS ester; 6-Carboxytetramethylrhodamine N-succinimidyl ester)

6-TAMRA-SE (6-TAMRA-NHS ester) is a fluorescent dye carrying the amine reactive group. 6-TAMRA-SE is one of the traditional fluorophores used for automated DNA sequencing^[1][2][3].

6-TAMRA-SE (6-TAMRA-NHS ester) is an amine-reactive form of tetramethylrhodamine. 6-TAMRA-SE (soluble in DMF and DMSO, absorption=546, emission=576 measured in MeOH =9.5×104 =9.5×104)^[1][3].
