5-(and-6)-Carboxyrhodamine 110, succinimidyl ester is a superior green fluorescent dye that readily reacts with a primary or secondary amine. For many applications, the dye is preferred over 5-(and-6)-carboxyfluorescein succinimidyl ester (5(6)-FAM) or FITC because of its exceptional photostability and fluorescence insensitivity to pH (4-9). See spectra and photostability data under #90081. Also see #90030, #90031, #90081 and #90084. See Figure 7.5 for spectra.
