6-TAMRA, SE (6-Carboxytetramethylrhodamine, Succinimidyl Ester), single isomer

The isomeric 6-TAMRA, SE is an amine-reactive form of tetramethylrhodamine. The single-isomer preparations of TAMRA are most important for high-resolution techniques such as DNA sequencing and capillary electrophoresis. 6-TAMRA is one of the traditional fluorophores used for automated DNA sequencing.
