Processing of plasmid-containing fluids |
摘要 |
Disclosed is a method for processing a plasmid-containing fluid comprising contacting the plasmid-containing fluid with two charged membranes and obtaining a plasmid-enriched fluid such as a purified plasmid. In an embodiment, the first charged membrane is positively charged, and the second charged membranes is positively or negatively charged membrane. In a preferred embodiment, both first and second charged membranes are positively charged. In another embodiment, the plasmid-containing fluid is contacted with two positively charged membranes and a third charged membrane. The present invention further provides a system and a kit for processing plasmid-containing fluids.
