A fluorescent dye
5-Carboxytetramethylrhodamine is a fluorescent dye that has commonly been used for the covalent labeling of oligonucleotides for DNA analysis.1 It displays excitation and emission maxima of 546 and 580 nm, respectively.2 5-Carboxytetramethylrhodamine has also been used in various fluorescence polarization assays and protein FRET experiments.2,3
