Plasmid Miniprep Purification Kit
Click to enlarge image(s)
Plasmid Miniprep Purification Kit contains a unique silica column and a high-efficiency lysis buffer system to yield up to 40 μg high purity plasmid DNA from 1 to 5 ml bacterial cultures. High-purity plasmid DNA can be obtained using this kit, without needing to precipitate, concentrate, or desalt.
  • Easy to operate:Spin Column format.
  • High yield:Can prepare 10~40 μg plasmid DNA from 1~5 ml culture.
  • High Purity:High purity plasmid DNA that can be used directly for automatic sequencing, in vitrotranscription, PCR and enzyme digestion or any other subsequent applications.
  • Fast:The whole process can be done within 10~15 minutes.
