5-Carboxytetramethylrhodamine, 5-TAMRA (CAS: 91809-66-4), is a long-wavelength dye, fluorescent dye for DNA, peptides and proteins. Amine-reactive. Used for oligonucleotide labeling and automated DNA sequencing applications. TAMRA is often used as FRET acceptor for FAM fluorophore. Free 5(6)-TAMRA (ab145282) and 6-TAMRA (ab145338) isomer. 5-TAMRA N-succinimidyl ester (ab145433) precursor. 5-TAMRA, SE and its conjugates yield bright, pH-insensitive orange-red fluorescence with good photostability. 5-TAMRA is the purified single isomer of 5(6)-TAMRA. It is widely used to label peptides and proteins. 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 5-TAMRA without the conventional chromatographic purification.
