Bio-Rad's high-quality EZ Load™ molecular rulers are essential tools for every classroom molecular biologist. These DNA size standards can be used as positive controls for electrophoresis and for determining the sizes of unknown DNA fragments.
EZ Load molecular rulers cover all your DNA fragment–sizing needs, from oligonucleotides to PCR products to plasmids. The standards are prediluted to a concentration appropriate for most electrophoresis runs and are available in five size ranges. To ensure easy and correct measurement of your sample sizes, most of these ladders include a visually distinct reference band.
