Product Description


  • Xylene Cyanol FF is used as a tracking dye to monitor the progress of electrophoresis separations. The tracking dye typically migrates with the DNA molecules around 5kb. Therefore, if you are monitoring the progress of longer electrophoresis runs, Xylene Cyanol FF is the tracking dye of choice!
  • NOTE: Tracking dyes may interfere with the ability to visualize the fragments that comigrate with them.
