Eluates from anion-exchange plasmid preparations (such as NucleoBond midipreps and maxipreps) contain high salt concentrations. Macherey-Nagel has developed a new vacuum-driven accessory, the NucleoSnap Finisher Midi/Maxi kits, that allows you to desalt and concentrate plasmid DNA in a few minutes without any loss of yield or quality. These kits are the fastest way to desalt and concentrate DNA after your NucleoBond plasmid DNA preps.
