How can I increase DNA concentration using QIAprecipitators of the HiSpeed Plasmid Kits?
FAQ ID -1061

Use 500 µl instead of 1 ml of Buffer TE for elution of plasmid DNA from the QIAprecipitator of the HiSpeed Plasmid Kits. If low copy plasmids are used, the lysates of two QIAfilter Cartridges can be filtered into one equilibrated HiSpeed Tip. HiSpeed Maxi Kits will result in higher DNA concentration than HiSpeed Midi Kits, because the QIAprecipitators in both kits (Midi- and Maxi Module) use the same elution volume.
