  • Product Information

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

    The DNA Ladder consists of a proprietary plasmid which is digested to completion with appropriate restriction enzymes to yield 11 bands suitable for use as molecular weight standards for agarose gel electrophoresis. This digested DNA includes fragments ranging from 25-766 base pairs. The 200 base pair band has increased intensity to serve as a reference point..

    • Recommended gel percentage range: 2-3.5%
    • Optimum separation on 3% 

    Quick-Load Purple Low Molecular Weight DNA Ladder visualized by ethidiumbromide staining on a 3% TBE agarose gel. Mass values are for 0.5µg/lane.
    Suggested Load: 10 µl/gel lane.
