Synonyms: 5(6)-Carboxy-tetramethylrhodamine

Common DNA labeling reagent, also used for protein labeling.

  • Alternate name: 5(6)-Carboxytetramethylrhodamine

Carboxytetramethylrhodamine (TAMRA) is a fluorescent dye that is a derivative of rhodamine. This methyl derivative emits in the red region of the spectrum and is often used to label oligonucleotides at the 5'- or 3'-ends, or internally. TAMRA has an absorbance maximum of 565 nm and an emission maximum of 580 nm. TAMRA-modified oligonucleotides play a particularly important role in both fluorescence resonance energy transfer (FRET) and real-time PCR applications.
