Other Notes

GenElute Plasmid Midi- and Maxiprep Kits offer a simple, rapid and cost-effective method for isolating plasmid DNA from E. coli cultures. These kits combine silica-based membrane technology with the convenience of a spin column format and deliver up to 350 μg (Midi) and 1.2 mg (Maxi) yield of high-copy plasmid DNA.


Bacterial cells are harvested via centrifugation and subjected to a modified alkaline-SDS lysis procedure followed by adsorbtion of DNA onto silca in the presence of high salts. Contaminants are then removed by a simple wash step. Finally, the bound DNA is eluted in water or Tris-EDTA buffer. The recovered plasmid DNA is predominately in its supercoiled form. There is no visual evidence of genomic DNA or RNA contamination.
