Product Information

Description



TriDye™ 1 kb Plus DNA Ladder is a pre-mixed, ready-to-load molecular weight marker containing 3 dyes which serve as visual aids to monitor the progress of migration during agarose gel electrophoresis.

The DNA Ladder consists of proprietary plasmids which are digested to completion with appropriate restriction enzymes to yield 19 bands suitable for use as molecular weight standards for agarose gel electrophoresis. This digested DNA includes fragments ranging from 100 bp to 10 kb. The 0.5, 1.0 and 3.0 kb bands have increased intensity to serve as reference points.

  • Recommended gel percentage range: 1-1.4%
  • Optimum separation on 1.2%

Product Notes

  1. The TriDye DNA 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.
  2. We recommend loading 5-10 μl (0.5-1.0 μg) of TriDye DNA ladder per gel lane.
  3. In general, it is recommended to load 1ul per mm of gel lane.
  4. TriDye DNA Ladder is stable for at least 6 months at 25°C.
  5. For long term storage, store at 4°C or -20°C. If stored at -20°C, mix well after thawing.
