GeneRuler™ 1 kb Plus DNA Ladder, ready-to-use with 6X TriTrack DNA Loading Dye

The Thermo Scientific™ GeneRuler 1 kb Plus DNA Ladder is a pre-mixed, ready-to-load molecular weight standard designed for accurate sizing and quantification of double-stranded DNA on agarose gels. With a size range of 75 bp to 20,000 bp, it includes 15 chromatography-purified DNA fragments that provide sharp, easy-to-visualize bands. This ladder is pre-formulated with 6X TriTrack DNA Loading Dye, allowing simultaneous sample loading and tracking without additional dye preparation.

The ladder features distinct dye components—Xylene Cyanol FF, Bromophenol Blue, and Orange G—to enable three-color tracking of DNA migration during electrophoresis. It is compatible with both standard and precast agarose gels and works efficiently with ethidium bromide and SYBR Safe DNA staining.
