Columns for NucleoBond Xtra Midi plasmid DNA purification kit.

Reliable plasmid purification from large quantities of cells with NucleoBond Xtra Midi and NucleoBond Xtra Midi EF.Multiple plasmid preps were performed in parallel from bacterial cultures containing varying quantities of cells (ODV200 vs. ODV600) using NucleoBond Xtra Midi, NucleoBond Xtra Midi EF, and the ZymoPURE II Plasmid Midiprep Kit, and analyzed by agarose gel electrophoresis. At both input levels, the NucleoBond Xtra kits provided higher and more consistent yields than the ZymoPURE II kit, and this performance advantage was particularly striking for the higher input amount (ODV400). ODV was calculated by multiplying the optical density of each culture (measured at 600 nm) times the culture volume.

Higher yields than Qiagen with NucleoBond Xtra Midi and NucleoBond Xtra Maxi.Plasmid DNA was purified from bacterial cultures using NucleoBond Xtra Midi, NucleoBond Xtra Maxi, and corresponding midiprep and maxiprep kits from Qiagen following the protocols for each kit (in each case, the maximum input volume specified by the corresponding kit protocol was processed). Yields of plasmid DNA were 60–100% higher with the NucleoBond kits than the Qiagen kits (Q Midi = Qiagen Plasmid Midi Kit, Q Maxi = Qiagen Plasmid Maxi Kit).
