The High-Speed Plasmid Advance Kit was designed for plasmid and cosmid DNA purification from 50-100 ml of cultured bacterial cells using a plasmid midiprep spin column system. This plasmid kit uses a modified alkaline lysis method and RNase treatment to obtain clear cell lysate with minimal genomic DNA/RNA contaminants. In the presence of chaotropic salt, plasmid DNA in the lysate binds to the glass fiber matrix of the plasmid spin column. Contaminants are removed with a Wash Buffer (containing ethanol) and the purified plasmid DNA is eluted by a low salt Elution Buffer, TE or water. Typical yields are 200-350 μg for high-copy number plasmid or 30-100 μg for low-copy number plasmid from 50 ml of cultured bacterial cells. DNA phenol extraction or alcohol precipitation is not required and the entire procedure can be completed within 35 minutes.

Quality Control
The quality of the High-Speed Plasmid Advance Kit 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 High-Speed Plasmid Advance 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 checked by electrophoresis.
