Quick-Load® Purple 1 kb DNA Ladder is a pre-mixed, ready-to-load molecular weight DNA marker containing one tracking dye. Tracking dye does not leave a shadow under UV light.

Quick-Load® Purple 1 kb DNA Ladder consists of proprietary plasmids, which are digested to completion with appropriate restriction enzymes to yield 10 bands suitable for use as molecular weight standards for agarose gel electrophoresis. The digested DNA includes fragments ranging from 0.5 to 10 kb. The 3 kb fragment has increased intensity to serve as reference band.

  • Recommended gel percentage range: 0.8-1.2%

  • Optimum separation on 1% 


1 kb DNA Ladder visualized by ethidium bromide staining on a 0.8% TAE agarose gel. Mass values are for 0.5 µg/lane.
Suggested Load: 10 µl/gel lane.
