Part of the ZymoPURE Plasmid Kits collection, the ZymoPURE – Express Plasmid Midiprep kit utilizes a patented alkaline lysis method for purifying up to 1.2 mg of transfection-grade plasmid DNA directly from E. coli culture without conventional cell-pelleting and resuspension steps. The ZP Express Lysis Buffer is simply added directly to the culture and the plasmid DNA is purified following neutralization and removal of debris using the patented ZymoPURE binding system. The plasmid DNA is rapidly bound onto a column with a vacuum or a centrifuge instead of a slow gravity flow column. Additionally, there is no alcohol precipitation step required and the elution is performed using a microcentrifuge. The ZymoPURE – Express Plasmid Midiprep kit’s fast and simple protocol enables the recovery of highly concentrated transfection-grade plasmid DNA in just 15 minutes. As an added convenience, the ZymoPURE – Express Plasmid Midiprep kit contains colored buffers that permit error-free visualization and identification of complete bacterial cell lysis and neutralization.
