BioVision’s BriteRuler™ 1 kb DNA Ladder is a ready-to-use formulation containing bromophenol blue as the tracking dye and is suitable for sizing linear double-stranded DNA fragments from 250 bp to 10 kb. The 1 kb and 3 kb bands have increased intensity to provide internal orientation. The mass of DNA in each band is provided (assuming a 0.5 µg/5 µl load) for approximate quantification in comparably intense samples of similar size. The DNA Ladder features 13 bands spanning the range from 250 bp to 10 kb. The recommended usage is 5 µl/Lane
