The PureLink® HiPure Plasmid Filter Maxiprep Kit is designed to isolate plasmid DNA of the highest purity from 100 to 500 mL of an overnight bacterial culture. The PureLink® HiPure Plasmid Filter Kits include HiPure Filter Columns, which combine filtration for clarification of the bacterial lysate with anion-exchange resin purification of plasmid DNA, in a single unit. The resulting plasmid DNA is of a quality equivalent to that obtained by purification with two passes through cesium chloride gradients—the most rigorous method for DNA purification. Purify high-quality DNA in less than two hours for transfections and other applications with no need for additional steps to remove contaminants like RNA, proteins, or endotoxins. Additionally, the elimination of phenol, chloroform, ethidium bromide, and cesium chloride from the protocol minimizes exposure to, and disposal of hazardous materials.
