5(6)-TAMRA, SE

5-(and-6)-Carboxytetramethylrhodamine, succinimidyl ester; CAS 246256-50-8

The succinimidyl esters of 5-TAMRA, 6-TAMRA or the mixed isomers are the primary labeling reagents for the preparation of orange fluorescent bioconjugates, including peptide, protein, nucleotide and nucleic acid conjugates, especially fluorescent antibodies and avidin derivatives used in immunochemistry. TMR dyes have also been widely used as acceptors for FAM fluorophores in a variety of FRET studies.
