FAQ: What are the differences in the four versions of 2-Log, 100 bp and 1 kb DNA Ladders that NEB sells?

These ladders come in four formats. Choose from the conventional ladder, the Quick-Load® version using either non-flourescing purple dye (B7024) or bromophenol blue as a tacking dye, or TriDye™ containing three dyes that serve as visual aids to monitor the progress of migration during agarose gel electrophoresis. Quick-load versions also include a vial of loading dye, free of charge.
