Thermo Scientific FastRuler DNA Ladders is a fast and convenient tool for double-stranded DNA sizing during electrophoresis. It's specifically engineered for rapid sizing and approximate quantification of DNA on both conventional agarose gels and high-throughput E-Gels (in 48- and 96-well formats).

The ladder is a mixture of five blunt-ended chromatography-purified individual DNA fragments. This allows you to achieve precise results faster, saving valuable lab time.

Highlights

  • Variety of available ranges (from ultra-low to high- range)
  • Fast separation (8 to 14 min)
  • Short separation distance (10 to 20 mm)
  • Sharp bands, easy-to-remember fragment sizes and quantities
  • Ready-to-use: premixed with 6X MassRuler DNA Loading Dye for direct loading
  • Stable at room temperature for up to 24 months

Sustainability features

Ready-to-use FastRuler DNA ladders can be stored at room temperature for up to 24 months. The ladder is shipped at ambient temperature, using optimized right-sized packaging and 100% recyclable packaging reducing waste.

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.
