Description:
TriDye™ 2-Log 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.
TriDye During Electrophoresis: On a standard 1% agarose gel in 1X TBE, xylene cyanol FF migrates at approximately 4 kb, bromophenol blue at approximately 300 bp and the orange G at approximately 50 bp. As the percentage of agarose changes, the migration rates of the dyes relative to migration rates of the DNA will change.
2-Log DNA Ladder visualized by ethidium bromide staining on a 1.0% TBE agarose gel. Mass values are for 1 µg/lane.
Effective Size Range: 100 bp to 10,002 bp
Source:
The TriDye 2-Log 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.

Notes
General notes:- TriDye 2-Log DNA Ladder is stable for at least 6 months at 25°C.
- For long term storage, store at 4°C or -20°C. If stored at -20°C, mix well after thawing.
Usage notes:- The TriDye 2-Log 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.
- We recommend loading 10 μl (1.0 μg) of TriDye 2-Log DNA ladder per gel lane.
FAQs
- 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?
