Invitrogen™ TO-PRO™-3 Iodide (642/661) - 1 mM Solution in DMSO

Invitrogen™ TO-PRO™-3 Iodide (642/661) - 1 mM Solution in DMSO

TO-PRO®-3 stain is a carbocyanine monomer nucleic acid stain with far-red fluorescence similar to Alexa Fluor® 647 or Cy®5 dyes. It is useful as a nuclear counterstain and dead cell indicator, and is among the highest-sensitivity probes for nucleic acid detection.

For use with equipment: Fluorescence Microscope
