5 - TAMRA, Special Formulation [5 - Carboxytetramethylrhodamine]
5-TAMRA is the purified single isomer of 5(6)-TAMRA. It is preferred for some complicated biological applications where reproducibility is more critical than material cost since the minor positional difference between 5-TAMRA and 6-TAMRA might affect some biological properties of the underlying conjugates.
