Takara NucleoBond Xtra Midi EF, 50 Preps

NucleoBond Xtra Midi EF (50) 50 preps for the isolation of endotoxin-free plasmid DNA - NucleoBond Xtra Midi Columns, NucleoBond Xtra Midi Column Filters, buffers, RNase A

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.
