Functional Activity:

5(6) ? TAMRA, SE is the amine-reactive, mixed isomer form of tetramethylrhodamine (TAMRA, or TMR). It is 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. TAMRA (TMR) dyes have also been widely used as acceptors for FAM fluorophores in a variety of FRET studies.
