Endotoxin Free Mini Kit (PEH100)
The Presto™ Endotoxin Free Mini Plasmid Kit was designed for transfection grade plasmid DNA purification from 1-5 ml of cultured E. coli cells using silica-membrane spin columns. A modified alkaline lysis method and RNase treatment are used to obtain clear cell lysate with minimal genomic DNA and RNA contaminants. In addition, an efficient endotoxin removal step is integrated in the procedure and endotoxins are precipitated in a proprietary reagent. TrueBlue Lysis Buffer (an optional color indicator) is included with the kit in order to prevent common handling errors, ensuring efficient cell lysis and neutralization. DNA phenol extraction or alcohol precipitation is not required and the entire procedure can be completed within 50 minutes. The purified endotoxin free plasmid DNA is ready for use in transfection, restriction enzyme digestion, ligation, PCR, and sequencing reactions.

The quality of the Presto™ Endotoxin Free 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™ Endotoxin Free Mini Plasmid Kit. Following the purification process, a yield of more than 25 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.
