DNA Extraction/Plasmid DNA Purification
The Geneaid™ Midi Plasmid Kit Endotoxin Free was designed for plasmid DNA purification and endotoxin removal using pre-packed anion-exchange resin maxiprep columns to purify plasmid DNA from 50-300 ml of cultured bacterial cells. 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. This endotoxin free plasmid kit 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 to the column and the contaminants are removed with the 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 and the purified plasmid DNA is suitable for Transfection, Sequencing Reactions, Ligation, PCR, and In-vitro Transcription, Microinjection, Restriction Enzyme Digestion and Gene Gun.
