General description

Sigma′s Lambda DNA Mixed Digest contains 10 fragments from 1,503 − 48,502 bp. Six ul of the ladder should be diluted in gel loading buffer and then loaded in a single lane on an agarose or polyacrylamide gel.


Lambda DNA Mixed Digest has been used for DNA electrophoresis.
Suitable for size determination of dsDNA by electrophoresis with either agarose or polyacrylamide gels.


Sigma′s Lambda DNA Mixed Digest is provided in a solution of 10 mM Tris-HCl (pH 8.0), with 1.0 mM EDTA.

Preparation Note

Bacteriophage lambda DNA was completely digested with by Apa I, Kpn I, Xba I and Xho I in separate reactions, sticky ends filled with DNA polymerase I Klenow (to prevent reannealing), mixed with uncut bacteriophage lambda DNA, and then purified by phenol extraction.

Other Notes

For optimal resolution, the recommended agarose gel concentration is 0.4%.

Storage Class

10 - Combustible liquids

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.

Choose the appropriate markers and ladders for nucleic acid size determination of samples separated by electrophoresis. Determine size of DNA, RNA and PCR-generated fragments using agarose or polyacrylamide gels.

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