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 conventional double-stranded DNA molecular weight markers. These standards have a size range of approximately 10 bp to 23,000 base pairs.
All markers and ladders come with a free separate tube of the unique purple gel loading dye.
Your benefit: This new dye does not cast UV shadows.
Advantages:
- Suitable for analysis of a wide range of DNAs
- Uniform band intensities and convenient band spacing
- Easy-to-identify reference bands
- Allows for DNA quantification
- Includes free Gel-Loading Dye
Our growing line of DNA Ladders includes the Fast DNA Ladder designed for use with fast electrophoresis systems.
