General description

Sigma′s PCR 20 bp Low Ladder contains 50 dsDNA fragments from 50 – 1,000 bases, evenly spaced in 20 bp repeats. Five μl of the ladder should be diluted in gel loading buffer and then loaded in a single lane on an agarose gel.

Application

PCR 20 bp Low Ladder has been used as a marker for DNA gel electrophoresis.

Components

Sigma′s PCR 20 bp Low Marker is provided in a solution of 10 mM Tris-HCl (pH 8.0), with 1.0 mM EDTA.

Other Notes

Contains 50 bands, 20–1,000 bp in exact 20 bp repeats.
For optimal resolution, the recommended agarose gel concentration is 2.5%.

Markers and Ladders for Gel Electrophoresis

We offers a variety of markers that aid size determination of samples separated by agarose and/or polyacrylamide gel electrophoresis. These products include markers for DNA, PCR fragments and RNA and can be concurrently run with the samples. All the markers stain well with common nucleic acid stains.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
