NEB offers a variety of DNA Ladders with sizes ranging from 25 bp to 40 kb for use in agarose gel electrophoresis. NEB also offers a wide range of double-stranded DNA molecular weight markers for conventional agarose gel electrophoresis. These standards have a size range of approximately 10 bp to 23,000 base pairs.
The typical pattern generated by each of the conventional markers is to the right. The number of fragments generated by each marker, as well as the specific fragment sizes for each of the conventional markers can be found on the product page.
Our growing line of DNA Ladders now includes the Mass and Fast DNA Ladders. The Mass DNA Ladder is ideal for size determination and mass quantification in the range of 0.5 – 10 kb. The Fast DNA Ladder is designed for use with fast electrophoresis systems.
The TriDye™ DNA Ladders are pre-mixed, ready-to-load molecular weight markers containing 3 dyes which serve as visual aids to monitor the progress of migration during agarose gel electrophoresis.
The Quick-Load® DNA Ladders are pre-mixed, ready-to-load molecular weight markers containing bromophenol blue as a tracking dye.
