Midi Fast-Ion Plasmid Kits, Endotoxin Free, IBI Scientific

About this item

IBI's Midi Fast-Ion Plasmid Kits are endotoxin free and use pre-packed ion-exchange resin columns to purify plasmid or cosmid DNA from bacterial cultures

Sample Size: 50 ml high-copy plasmid/100 ml low-copy plasmid
Operation: Gravity Flow Column
Expectant Yield: 200 µg of plasmid DNA
Operation Time: 120 minutes or less

The Midi Fast Ion Plasmid Kit uses pre-packed ion-exchange resin columns to purify plasmid or cosmid DNA from bacterial cultures. In this process, the modified alkaline lysis method and RNase treatment are used for creating cleared lysate with minimal genomic DNA and RNA contaminants. Using a gravity-flow procedure, the plasmid DNA in crude lysate has been bound to the column. The contaminants can be washed off with a wash buffer. Finally, the purified DNA is eluted by a high salt buffer and then precipitated with isopropanol for desalting. The entire procedure can be completed in less than two hours. The purified plasmid DNA is suitable for transfection, sequencing reactions, PCR, and in-vitro transcription.
