Thermo Scientific FastRuler Ultra Low Range DNA Ladder is specifically designed for fast sizing and approximate quantification of double-stranded DNA in 48 well (or 96-well) high throughput gels, as well as in conventional agarose gels. The ladder is a mixture of five blunt-ended chromatography-purified individual DNA fragments that are easily resolved in a short separation distance (10 to 20 mm) after an 8 to 14 minutes run on the appropriate agarose gel.

The ladder is especially useful for electrophoresis of PCR products.

FastRuler Ultra Low Range DNA Ladder, ready-to-use contains dephosphorylated DNA fragments and is ideal for forward 5-end labeling with T4 Polynucleotide Kinase (see the Certificate of Analysis for the detailed labeling protocol).
