E.Z.N.A.® Plasmid DNA Midi Kit

The E.Z.N.A. Plasmid Midi and Maxi Kits can isolate up to 250 μg and 1.2 mg of plasmid DNA from 50 mL and 200 mL bacterial cultures, respectively. These kits use a modified alkaline lysis method to lyse the cells and separate genomic DNA from plasmid DNA. Cellular debris are removed by centrifugation, and the protocol follows a simple bind, wash, and elute procedure to deliver high-quality

plasmid DNA. The system not only eliminates the time-consuming isopropanol precipitation step required by gravity flow columns but also the need for expensive accessories. Purified plasmid DNA is suitable for automated fluorescent DNA sequencing (typical reads exceed 800 bp), restriction enzyme digestion, ligation, PCR, in-vitro transcription, transformation, and other applications.
