Plasmid 25-mini Plasmid DNA Extraction Kit

The Thermo Scientific GeneJET Plasmid Miniprep Kit uses unique silica-based membrane technology in the form of a convenient spin column. The kit recovers up to 20 µg of high copy number plasmid DNA per isolation procedure.


• Efficient: high yields of up to 20 µg of high-quality plasmid DNA
• Fast: the procedure takes less than 14 minutes
Convenient – ​​no phenol/chloroform extraction or alcohol precipitation required
• Pure: purified DNA is immediately ready to use


  • Rapid isolation of high purity plasmid DNA suitable for all conventional molecular biology procedures including:
  • FastDigest or conventional restriction digestion
  • Automated fluorescent and radioactive sequencing
  • CPR
  • In vitro transcription
  • Transformation


A bacterial culture is harvested and lysed. The lysate is then clarified by centrifugation and applied to the silica column to selectively bind DNA molecules at high salt concentrations. Adsorbed DNA is washed to remove contaminants and pure plasmid DNA is eluted in a small volume of elution buffer or water. The purified DNA is ready for immediate use in all molecular biology procedures, including rapid and conventional restriction enzyme digestion, PCR, in vitro transcription, transformation, and automated sequencing.
