Amine-reactive form of single isomer carboxyrhodamine 110, useful in DNA sequencing. For many single-dye-labeling applications, the dye is preferred over other green fluorescent dyes including fluorescein and Alexa 488 because of its exceptional photostability and fluorescence insensitivity to pH (4-9). See spectra and photostability data under #90081. See Figure 7.5 for spectra.
