Thermo Fisher continues to expand its DNA isolation kits
Thermo Fisher Scientific Inc., the world leader in serving science, announced the launch of its new PureLink Fast Low-Endotoxin Plasmid Purification Midi and Maxi Kits, further strengthening its line of low-endotoxin plasmid DNA isolation products. The kits offer researchers dramatically accelerated isolation of plasmid DNA compared to current standard protocols. With the PureLink kits, researchers can isolate transfection-quality plasmid in about 30 minutes, up to 0.4 mg for midi scale and up to 1.5 mg for maxi scale preparation, enabling researchers to obtain high yields of low-endotoxin DNA in significantly less time and without a tedious alcohol precipitation step. The technology behind the faster isolation time is Thermo Fisher’s innovative advanced silica membrane-based columns, utilized in combination with the Thermo Scientific FastVac vacuum manifold, enabling isolation of transfection-quality plasmid in as little as 30 minutes. Traditional anion-exchange resin-based columns rely on gravity flow to purify the DNA, and also require an isopropanol precipitation step, which takes more than two hours.
