Geneaid™ Midi Plasmid Kit Endotoxin Free (25 rxns)
The Geneaid™ Midi Plasmid Kit Endotoxin Free uses pre-packed anion-exchange resin 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. A modified alkaline lysis method and RNase treatment are used to obtain clear cell lysate with minimal genomic DNA/RNA contaminants. Using an efficient gravity-flow procedure, plasmid DNA is bound to the column and contaminants are efficiently removed. The purified plasmid DNA is eluted then precipitated with isopropanol for desalting. The entire procedure can be completed without ultracentrifuges, HPLC or other toxic reagents and the purified plasmid DNA is suitable for transfection, sequencing reactions, ligation, PCR, in-vitro transcription, microinjection, restriction enzyme digestion and gene gun.

Quality Control

The quality of the Geneaid™ Midi Plasmid Kit (Endotoxin Free) is tested on a lot-to-lot basis according to Geneaid's ISO-certified quality management system. Plasmid DNA from a 100 ml overnight E. coli (DH5α) culture, containing plasmid pBluescript (A600 > 2 U/ml) is purified using the Geneaid™ Midi Plasmid Kit. Following the purification process, a yield of more than 400 μg is obtained and the A260/A280 ratio is between 1.8-2.0. The purified plasmid DNA (1 µg) is used in EcoRI digestion, and analyzed by electrophoresis.

Plasmid Midi Kit Endotoxin Free Functional Test Data

Figure 1. Plasmid DNA from a 100 ml overnight E. coli (DH5α) culture, containing plasmid pBluescript (OD600 = 3.65) was purified using the Geneaid™ Midi Plasmid Midi. The purified supercoiled plasmid DNA was used in EcoRI digestion. Plasmid DNA yield was determined by spectrophotometer and analyzed by electrophoresis on a 1% agarose gel. M = Geneaid 1 Kb DNA Ladder
