Amine-Reactive fluorescent probe that can be coupled to biomolecules. The excitation and emission spectra of carboxyrhodamine 6G (CR 6G) fall between those of fluorescein and tetramethylrhodamine and with higher fluorescence quantum yield than tetramethylrhodamine conjugates. With a peak absorption at 525 nm, conjugated probes of carboxyrhodamine 6G are an excellent match to the 514 nm spectral line of the argon-ion laser.
