Presto™ Mini Plasmid Kit (PDH100, PDH300)
This miniprep Plasmid Kit was designed for plasmid DNA purification from 1-7 ml of cultured bacterial cells. For processing larger volumes, the Presto™ Midi 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, neutralization and maximum plasmid product yield. The Presto™ Mini 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 mini 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. DNA phenol extraction or alcohol precipitation are not required and the entire procedure can be completed within 15 minutes.

The quality of the Presto™ Mini Plasmid Kit is tested on a lot-to-lot basis according to Geneaid's ISO-certified quality management system. Plasmid DNA from a 4 ml overnight E. coli (DH5α) culture, containing plasmid pBluescript (A600 > 2 U/ml) is purified using the Presto™ Mini Plasmid Kit. Following the purification process, a yield of more than 30 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.
