Quick-Load® Purple DNA Ladders

With our Quick-Load Purple DNA ladders, you can:

  • Quickly determine the size of your DNA, using the evenly-spaced bands and easily-identifiable reference bands
  • Improve your ability to separate fragments, as our new & improved purple loading dye sharpens bands
  • Improve the visibility of the bands, as our purple dye leaves no UV shadow
  • Save money, as NEB’s cost per lane is less than other commercially available ladders
  • NEB’s purple dye runs at the same migration rate as bromophenol blue, making it an easy migration reference. 

This format is available for the Low Molecular Weight, 50 bp, 100 bp, 1 kb, and 2-log DNA ladders. All Include a vial of Gel Loading Dye, Purple (6X), no SDS
