5-TAMRA cadaverine deuterium-labeled-ketone 722 SMILES: [O-]C(=O)C1=CC=C(C=C1C1=C2C=C3CCC[N+]4=C3C(CCC4)=C2OC2=C3CCCN4CCCC(C=C12)=C34)C(=O)NCCCN=[N]#N Purity (HPLC):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.
