Thermo Scientific GeneRuler Express DNA Ladder is designed for fast separation (in 5 to 15 minutes at 23 V/cm) of double-stranded DNA fragments in agarose gels (see Figure 1 and Table 1 in Supporting Data). The band pattern of express ladders is not affected by the composition of electrophoresis buffer, voltage, or gel percentage. The ladder is a mixture of chromatography-purified individual DNA fragments.

GeneRuler Express DNA Ladder can be labeled radioactively with T4 Polynucleotide Kinase (see protocol in Resources).

The ladder is supplied with 6X DNA Loading Dye for sample DNA.


• Ideal for both DNA sizing and approximate quantification
• Ideal for fast separation under a wide range of electrophoresis conditions
• Sharp bands
• Bright reference bands
• Supplied with loading dye for sample DNA
For Research Use Only. Not for use in diagnostic procedures.
