Product Information

Quick-Load® 1 kb Plus DNA Ladder is a pre-mixed, ready-to-load molecular weight marker containing bromophenol blue as a tracking dye.

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 bands.

NEB also offers a Quick-Load version of this ladder with purple dye.

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

Notes
1. Preparation of DNA: The double-stranded DNA is digested to completion with appropriate restriction enzymes, phenol extracted and equilibrated in storage buffer.
2. In general, it is recommended to load 1µl per mm of gel lane.
3. The Quick-Load DNA Ladder is not intended for precise quantification of DNA mass but can be used for approximating the mass of DNA in comparably intense samples of similar size.
4. Quick-Load 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.
6. We recommend loading 5-10 μl (0.5-1.0 μg) of Quick-Load 1 kb Plus DNA Ladder per gel lane.
