Bio-Rad provides three types of molecular rulers: Standard, EZ Load™, and AmpliSize® Rulers
Standard Molecular Rulers are precisely sized DNA, ready for dilution. EZ Load™ Molecular Rulers are ready-to-load. They include a vial of 5X sample buffer for preparing your own samples. AmpliSize® Molecular Rulers contain ten bands (at 50, 100, 200, 300, 400, 500, 700, 1,000, 1,500, and 2,000 bp) blunt-ended DNA with 50% GC content.
To ensure correct sizing of bands in samples, most of these DNA ladders include a visually distinct reference band.
