Product Information

Description

The BstEII digest of lambda DNA (cI857 ind 1 Sam 7) yields 14 fragments suitable for use as molecular weight standards for agarose gel electrophoresis (1). The approximate mass of DNA in each of the bands is provided (assuming a 1.0 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.

  • Recommended gel percentage range: 0.6-1.2%
  • Optimum separation on 0.8%

Product Notes

  1. 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 dH20 and subsequently heated. Temperatures > 60°C may cause denaturation.
  2. The cohesive ends of fragments 1 and 4 may be separated by heating to 60°C for 3 minutes.

FAQs & Troubleshooting

FAQs

  1. 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?
  2. How can I quantify the amount of DNA in each band of a marker?
  3. Why does my Lambda DNA molecular weight marker appear smeared and not represent the correct banding pattern?
  4. Can I use Midori Green with the DNA Ladders from NEB?
  5. Can I use SYBR® and/or GelRed® dyes with the DNA Ladders from NEB?
  6. Why is my DNA Ladder floating out the wells? Why are there no bands visible in my DNA ladder gel lane?

Tech Tips

Heat at 60C for 3 minutes to separate the cohesive ends of fragments 1 and 4.

To make it ready-to-load, dilute in TE buffer instead of water.
