IB47125 Endotoxin Free Maxi Fast-Ion Plasmid Kit for 25 Preparations

The fast ion plasmid maxi kit (endotoxin free) uses pre-packed anion-exchange resin columns to purify plasmid DNA from 100-250 ml of cultured bacterial cells. Modified Alkaline Lysis method (1) and RNase treatment are used 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 PW 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 2.5 hours 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. The quality of the Fast Ion Plasmid Maxi Kit (Endotoxin Free) is tested on a lot-to-lot basis by isolating plasmid DNA from a 100 mL overnight E. coli (DH5 alpha) culture, containing plasmid pBluescript (A600 greater than 2 U/ml). More than 400 microgram of plasmid DNA is quantified with a spectrophotometer. The purified plasmid (1 microgram) is used in EcoR I digestion, and checked by electrophoresis. Caution: During operation, always wear a lab coat, disposable gloves, and protective goggles. Format: ion-exchange resign column. Purity: equal to that obtained by 2XCsCl-Gradient centrifugation. Operation time: 120 minutes or less. Applications: transfection, sequencing, in-vitro transcription, microinjection, restriction digestion.
