Variable-sized DNA fragments for applications where a custom DNA size standard is required.

• Broad range: 10 to 20000 bp
• Sharp peaks during capillary electrophoresis, sharp bands during gel electrophoresis
• Precise DNA concentration
• Chromatography-purified individual DNA fragments

Thermo Scientific NoLimits is a collection of 36 highly-purified individual DNA fragments ranging from 10 to 20,000 bp. Unlike other vendors, where custom standards are produced by PCR, Thermo Scientific NoLimits DNA fragments are produced using specifically designed plasmids purified by patented technology. Plasmid DNA, digested with Thermo Scientific Restriction Enzymes, is chromatography-purified to prepare the individual DNA fragments from the digestion mixture. The results are extremely pure DNA fragments, free of any truncated or degraded molecules. These custom DNA fragments are the best custom standards for applications ranging from electrophoresis (both gel and capillary) to HPLC and beyond.
