5-TAMRA cadaverine

5-TAMRA cadaverine is the purified single isomer of 5(6)-TAMRA cadaverine mixture. It is often used as a building block for developing fluoresceinated bioconjugates. It is also a fluorescent transglutaminase substrate to label proteins by transaminidation. It is preferred for some complicated biological applications where reproducibility is critical since the minor positional difference between 5-isomer and 6-isomer might have biological implications. TAMRA (TMR) is one of the most popular fluorophores used in various bioconjugations. TAMRAis a bright orange fluorophore.
