Loading Dye – DNA Stain

  • 10x bromophenol blue
  • Mix with samples before loading
  • perfect for routine electrophoresis

DNA Loading Dye contains 10x bromophenol blue, the standard tracking dye for electrophoresis. The charge-to-mass ratio of bromophenol blue allows it to co-migrate with smaller molecules within agarose and PAGE gels (e.g. at 300bp in a standard 1% agarose TBE gel) which, with its conspicuous dark blue colour, makes it the perfect tracking dye to monitor the progress of electrophoresis runs.
