Thermo Scientific MassRuler Express LR Forward and Reverse DNA ladders are specially designed for fast and reliable DNA quantification in short separation distances under various electrophoresis conditions. In the forward versions, the mass of each DNA fragment is directly proportional to the fragment size, whereas in the reverse versions, the mass is inversely proportional to fragment's size.

The intensity of the fragment in each ladder is calibrated against a standard that guarantees the precise quantity of each band. The ladders are mixtures of chromatography-purified, individual DNA fragments.

Highlights

Accurate DNA sizing and quantification – DNA ladder fragments are quantified spectrophotometrically
Fast and reliable DNA quantification – short separation distances under various electrophoresis conditions
Sharp bands
Easy-to-remember fragment sizes and quantities
Ready-to-use – premixed with 6X MassRuler DNA Loading Dye for direct loading and room temperature storage
Supplied with loading dye for sample DNA
