6-TAMRA is the purified single isomer of 5(6)-TAMRA. It is widely used to label nucleotides and nucleic acids. 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. Currently AAT Bioquest is using a proprietary process to synthesize isomer-free 6-TAMRA without the conventional chromatographic purification.
