Endotoxins are copurified during plasmid preparations from bacterial lysates. Since they interfere with eukaryotic cell survival, endotoxin reduction is essential prior to cell transfection. Macherey-Nagel has developed a new column format and a novel buffer chemistry to enable vacuum-processed isolation of transfection-grade plasmid DNA in a midiprep format.

NucleoBond Xtra Midi (10) 10 preps for the isolation of plasmid DNA - NucleoBond Xtra Midi Columns, NucleoBond Xtra Midi Column Filters, buffers, RNase A

NucleoSpin Plasmid Transfection-grade is a fast miniprep kit that uses a new technology developed by Macherey-Nagel to reduce the level of endotoxins co-purified during plasmid preparations from bacterial lysates. Since endotoxins interfere with eukaryotic cell survival, endotoxin reduction is essential prior to cell transfection.
