产品描述

TOTO®-3 stain is a carbocyanine dimer with far-red fluorescence similar to Alexa Fluor® 647 or Cy® 5 dyes that is easily

distinguished from fluorescein and rhodamine. It is useful as a nuclear counterstain and dead cell indicator, and is among

the highest-sensitivity probes for nucleic acid detection.

Important Features of TOTO®-3 Include: • Nonfluorescent in the absence of nucleic acids • Very bright fluorescence signal • Ideal for flow cytometry and fluorescence microscopy •Long-wavelength fluorescence is well separated from green and red fluorophores • Cell-impermeant • Excitation⁄Emission: 640⁄660 nm

Many Applications TOTO®-3 stain and the other dimeric cyanine stains have wide applicability due to their low background and bright fluorescence.

Uses include staining of nucleic acids on solid supports, prestaining of samples for gel or capillary electrophoresis, and nuclear

counterstaining in multiple-label experiments. Electrophoresis of samples prestained with TOTO®-3 or other dimeric cyanine dyes

is possible due to the unusual stability of the dye-Nucleic Acid complexes.
