GeneRuler DNA Ladder 标准分子量选购指南：

Thermo Scientific GeneRuler Express DNA Ladder is recommended for sizing and approximate quantification of a double-stranded DNA in the range of 100 bp to 5,000 bp on agarose gels. The DNA ladder consists of 9 DNA fragments and is provided with 6X TriTrack DNA Loading Dye.

Highlights of Express DNA Ladder

• Easy visualization—three-color tracking of DNA migration during electrophoresis with 6X TriTrack DNA Loading Dye (contains Xylene Cyanol FF, Bromophenol Blue, and Orange G)

• Simplicity—one loading dye for a variety of samples

• Sharp bands—clear results with mixtures of individual chromatography-purified DNA fragments

Product use

This double-stranded DNA ladder is compatible with 1% standard and precast agarose slab gels and can be visualized after ethidium bromide or SYBR Safe staining. A uniform intensity of bands and bright reference bands allow easy sizing and orientation. A defined amount of DNA in each band enables approximate quantification of sample DNA.
