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
Convenient—ready-to-load DNA Ladder is premixed with 6X TriTrack DNA Loading dye and stable at room temperature for up to 6 months

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.
For Research Use Only. Not for use in diagnostic procedures.

Frequently asked questions (FAQs)

Are the Thermo Scientific DNA ladders compatible with GelRed and GelGreen gel stains?

The GelRed or GelGreen nucleic acid dyes can be used with our DNA Ladders. Nucleic acid binding dyes can affect DNA migration during electrophoresis, therefore we highly recommend post-staining of gels. Please follow the gel staining protocol provided by the manufacturer of nucleic acid gel dyes.

Which Thermo Scientific DNA ladders are optimal for fast electrophoresis separation?

For fast sizing and quantification of double-stranded DNA, we recommend using FastRuler DNA Ladders. These ladders are easily resolved in a short separation distance after an 8-14 min run.

What is the recommended voltage for electrophoresis with Thermo Scientific DNA and RNA ladders? What does V/cm mean?

Each of Thermo Scientific DNA and RNA ladders has a recommended voltage given in V/cm. Please refer to the gel picture in the product information sheet. V/cm stands for the amount of voltage recommended per cm of the distance between the two electrodes of the gel box (not gel length).

What are the end functional groups of Thermo Scientific DNA and RNA ladders?

Thermo Scientific DNA and RNA ladders have 5′-phosphate and 3′-hydroxyl groups.
