Product Information
Description
A number of proprietary plasmids are digested to completion with appropriate restriction enzymes to yield 12 bands suitable for use as molecular weight standards for agarose gel electrophoresis. The digested DNA includes fragments ranging from 100-1,517 base pairs. The 500 and 1,000 base pair bands have increased intensity to serve as reference points. The approximate mass of DNA in each of the bands is provided (assuming a 0.5 μg load) for approximating the mass of DNA in comparably intense samples of similar size.
Comes supplied with 1 vial of Gel Loading Dye, Purple (6X), no SDS.
NEB also offers a Quick-Load version of this ladder with purple dye.
- Recommended gel percentage range: 1.2-3%
- Optimum separation on 2%
- This product is related to the following categories:

Product Notes
- This ladder was not designed for precise quantification of DNA mass but can be used for approximating the mass of DNA in comparably intense samples of similar size.
- We recommend loading 0.5 μg of 100 bp DNA Ladder diluted in sample buffer.
- All fragments have 4-base, 5´ overhangs that can be end labeled using T4 Polynucleotide Kinase (#M0201) or filled-in using DNA Polymerase I, Klenow Fragment (#M0210) (1). Use α-[32P] dATP or α-[32P] dTTP for the fill-in reaction.
- 100 bp DNA Ladder is stable for at least 3 months at 4°C.
- For long term storage store at -20°C. If samples need to be diluted, use TE or other buffer of minimal ionic strength. DNA may denature if diluted in dH2O.
- Due to the limitations of the acrylamide gel technology, one or two extra bands may be visible on the DNA ladders when run on a polyacrylamide gel.

10mM EDTA
3.3mM Tris-HCl (pH 8.0@25°C)

FAQs & Troubleshooting
FAQs
- Why are there extra bands visible on polyacrylamide gels?
- Why is the separation of the lower bands incomplete?
- What are the overhangs on the DNA ladder fragments? Can I end-label them using the T4 polynucleotide kinase (PNK)? What about the Klenow fragment?
- Why are the DNA ladders showing up on my Southern blot? What is the sequence or composition of the ladder bands?
- How can I quantify the amount of DNA in each band of a marker?
- Can I use Midori Green with the DNA Ladders from NEB?
- Can I use SYBR® and/or GelRed® dyes with the DNA Ladders from NEB?
- Why is my DNA Ladder floating out the wells? Why are there no bands visible in my DNA ladder gel lane?
- What are the differences in the four versions of the 1 kb Plus (formerly called the 2-Log DNA Ladder), 100 bp and 1 kb DNA Ladders that NEB sells?
Tech Tips
To make it ready-to-load, dilute in TE buffer instead of water.
