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 is digested with Thermo Scientific Restriction Enzymes, and the individual DNA fragments are chromatography-purified from the digestion mixture. As a result, we offer exceptionally pure DNA fragments that are free of any truncated or degraded molecules. Our custom DNA fragments are the best choice for applications, ranging from electrophoresis (both gel and capillary) to HPLC and beyond.
