General description

Sigma′s 1 kb Ladder contains 11 fragments consisting of 500 bp repeats from 0.5 to 3 kb, 1 kb repeats from 3 to 6 kb, and 2 kb repeats from 6 to 10 kb. In nucleic acid gel electrophoresis, five μl of the marker should be diluted in gel loading buffer and then loaded in a single lane on an agarose or polyacrylamide gel. Suitable for use in Northern and Southern blotting. All DNA markers can be stained with ethidium bromide, SYBR® Green, and Nancy-520.

Application

1 kb DNA Ladder has been used as a molecular marker to determine the molecular weight and size of double stranded DNA during gel electrophoresis.

Components

Sigma′s 1kb Ladder is provided in a solution of 10 mM Tris-HCl (pH 8.0), with 1.0 mM EDTA.

Other Notes

For optimal resolution, the recommended agarose gel concentration is 0.75%.

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.
