Method of plasmid recovery and apparatus for doing so |
摘要 |
A process for the recovery of plasmids or other DNA from cells using a first filtration step to remove the cellular debris and other large cellular components and then an ultrafiltration step to capture the plasmids or other DNA on the surface of the ultrafiltration membrane where they may be recovered. An apparatus is also taught for enacting the process and comprises an upper microfiltration or coarse filtration membrane and a lower ultrafiltration membrane. The driving force may be the same for both filters or different and may be done sequentially or simultaneously.
