Bacterial Transformation
Protocol
- Thaw 100 μL of competent cells (per transformation) on ice just before they are needed;
- Add DNA (max 20μl) thawed cells and mix by flicking the side of the tube. Leave on ice for 30 minutes;
- Heat shock 5 minutes at 37 degrees Celsius;
- Place on ice for 5 minutes;
- Add 250ul SOC medium to each tube;
- Incubate for 30 to 60 minutes with shaking at 37 degrees Celsius (note that for Kanamycin containing plasmids always use one hour);
- Spin down to remove all supernatant except approximately 100 μL;
- Plate approximately 50 μL on antibiotic plates;
- Grow overnight at 37 degrees Celsius.
