Presto™ Midi Plasmid Kit (Endotoxin Free)

DNA Extraction/Plasmid DNA PurificationThe Presto™ Midi Plasmid Kit Endotoxin Free was designed for Plasmid DNA Purification and endotoxin removal from 50-150 ml of cultured bacterial cells using an efficient plasmid midiprep system. For processing smaller volumes, the Presto™ Mini Plasmid Kit is also available. Both plasmid kits include TrueBlue Lysis Buffer (an optional color indicator) to prevent common handling errors, while ensuring efficient cell lysis and neutralization. The Presto™ Midi Plasmid Kit Endotoxin Free uses a modified alkaline lysis method and RNase treatment to obtain clear cell lysate with minimal genomic DNA/RNA contaminants. Using an efficient gravity-flow procedure, plasmid DNA in the crude lysate is bound by the plasmid midi column and the contaminants are removed with PMC Buffer. The purified plasmid DNA is eluted by a high salt buffer and then precipitated with Isopropanol for desalting. The entire procedure can be completed in 80 minutes without ultracentrifuges, HPLC or other toxic reagents.

QUALITY CONTROL
The quality of the Presto™ Midi Plasmid Kit Endotoxin Free is tested on a lot-to-lot basis according to Geneaid's ISO-certified quality management system. Plasmid DNA from a 50 ml overnight E. coli (DH5α) culture, containing plasmid pBluescript (A600 > 2 U/ml) is purified using the Presto™ Midi Plasmid Kit. Following the purification process, a yield of more than 200 μg is obtained and the A260/A280 ratio is between 1.8-2.0. The purified plasmid (1 µg) is used in EcoRI digestion, and analyzed by electrophoresis.
