Description: 5-TAMRA (5-Carboxytetramethylrhodamine) (5-Carboxytetramethylrhodamine) yields bright, pH-insensitive orange-red fluorescence (approximate excitation/emission maxima ~546/579) with good photostability. Target: Others. Smiles: CN(C)c1ccc2c(-c3ccc(cc3C([O-])=O)C(O)=O)c3ccc(cc3[o+]c2c1)N(C)C

Free acid form of 5-carboxytetramethylrhodamine single isomer. Widely used fluorophore for preparing bioconjugates, especially fluorescent antibody and avidin derivatives used in immunochemistry. Used as a dye for oligonucleotide labeling and automated DNA sequencing applications.

5-TAMRA is the purified single isomer of 5(6)-TAMRA. the minor positional difference between 5-TAMRA and 6-TAMRA might affect some biological properties of the underlying conjugates.

5-Carboxytetramethylrhodamine is a fluorescent dye that has commonly been used for the covalent labeling of oligonucleotides for DNA analysis. It displays excitation and emission maxima of 546 and 580 nm, respectively. 5-Carboxytetramethylrhodamine has also been used in various fluorescence polarization assays and...
