Addgene: Protocol - Bacterial Transformation
2017年11月13日 · Scientists have made many genetic modifications to create bacterial strains that can be more easily transformed and that will help to maintain the plasmid without rearrangement of the plasmid DNA.
Bacterial Transformation Workflow - Thermo Fisher Scientific
If the E. coli strain is growing fast (such as Mach1) then plasmid can be isolated the same day, otherwise minipreps are incubated overnight and high-quality plasmids are isolated using commercial miniprep kits. Colonies need to be further screened for the presence of the desired DNA construct and to confirm correct sequence.
