Stable, long wavelength, water soluble fluorophore for use in DNA-labeling, cell staining and protein labeling applications.

Despite having a rhodamine nucleus, this probe has excitation and emission wavelengths similar to fluorescein (green color fluorescence), making it useful in detection systems employing fluorescein filter sets. For more information about this fluorophore, see the references below.
