Invitrogen™ PureLink™ HiPure Plasmid Maxiprep Kit

The PureLink HiPure Plasmid Maxiprep Kit is designed to isolate transfection-grade plasmid DNA from E. coli. The Maxiprep Kit protocol will typically yield 500–850 μg plasmid DNA from 100–200 mL bacterial culture, at purity that is comparable to that achieved by two passes through cesium chloride gradients.

• Labor and time saving- no need for extra steps to remove endotoxin and other contaminants
• High-purity, low-endotoxin product- pure enough for mammalian cell transfection
• Versatility—purify any type and size of plasmid DNA, including BAC, bacmids, and ssM13 DNAs

Anion-exchange chromatography for plasmid purification

• PureLink HiPure Plasmid DNA Purification Kits use patented anion-exchange resin to purify plasmid DNA to a level equivalent to two passes through CsCl gradients
• Resin combines excellent capacity with a fast flow rate, high resolution, high yield, and efficient endotoxin removal
• Plasmid preparations can typically be completed in less than 2 hours

Contaminant-free DNA

• Unlike cesium chloride gradient protocols, PureLink HiPure Plasmid Purification Systems do not use troublesome solvents to work with and to dispose of
• Typically, plasmid DNA prepared using the PureLink HiPure Plasmid Midiprep Kit will have an A₂₆₀/A₂₈₀ ratio of >1.80, indicating that the DNA is reasonably free of proteins that might interfere with downstream applications
• Endotoxin levels are typically within 0.1–1 EU/μg, making this plasmid DNA ideal for mammalian cell transfection
• Purification time is two hours
