GenElute™ Endotoxin-free Plasmid Maxiprep Kit
SIGMA/PLEX15 - sufficient for 15 purifications
Synonym: GenElute™ Endotoxin-free Plasmid Kits; Gen Elute
Product Type: Chemical
Comparison of time required per isolation using different Endotoxin-free plasmid isolation systems. Plasmid DNA was isolated following each manufacturers recommended protocol. Each system was tested multiple times and the average preparation time is shown here.
Comparison of transfection efficiencies of plasmids prepared with different Endotoxin-free isolation methods.
The data shows the average of six replicates for each named isolation method. All transfections were in CHO-K1 cells. The OD measurements were taken at 420 nm and the units of β-gal/plate were found using our β-Galactosidase Reporter Gene Activity Detection Kit. The cells were grown to ~60-75% confluency and transfected using 3 μg of plasmid DNA/15 μg of Escort IV. β-Gal activity was determined ~60-70 hour post-transfection. Error bars are the standard deviation of the 6 replicate wells tested.

| General description: | The GenElute Endotoxin-free Plasmid Kit offers a simple, rapid, cost effective method for purifying plasmid DNA with ≤0.1 EU/μg DNA for high efficiency transfection. Endotoxins (also known as lipopolysaccharides or LPS) are often co-purified with plasmid DNA and significantly reduce transfection efficiencies in endotoxin-sensitive cell lines. Recombinant E. coli is harvested from an overnight culture by centrifugation and subjected to a modified alkaline-SDS lysis procedure to produce a cleared lysate. Endotoxins are removed from the cleared lysate with simple extraction-phase separation steps. Plasmid DNA is further purified by adsorption onto silica in the presence of high salts. After a simple spin-wash step, the bound plasmid DNA is eluted in endotoxin-free water. Up to 1.2 mg of endotoxin-free plasmid DNA may be prepared from 25-200 mL of culture. The recovered plasmid DNA is predominately in its supercoiled form. The DNA is ready for immediate use in downstream applications such as transfection, restriction digestion, cloning, sequencing, and PCR amplification. |
