E.Z.N.A.® Plasmid DNA Midi Kit

The E.Z.N.A.® Plasmid DNA Midi Kit utilizes the convenient spin-column format to deliver high-quality plasmid DNA following a simple bind-wash-elute procedure without need for expensive accessories. The yields vary according to plasmid copy number, E. coli strain, and growth conditions. 15-50 mL of bacterial cultures in LB medium typically produces up to 200 µg of high copy number plasmid DNA. Up to 100 mL of culture may be processed when working with low copy number plasmid. The system uses centrifugation or vacuum technology for plasmid purification and eliminates the time-consuming gravity-flow columns that require alcohol precipitation. 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.
