Bacterial Transformation
- 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°Celsius. (Note that for Kanamycin containing plasmids always use one hour)
- Spin down to remove all supernatant except approximately 100 μL
- Plate approximately 30 μL on each of two antibiotic plates
- Grow overnight at 37°Celsius
For this protocol we used a couple of controls
- Positive Control - pBluescript in TOP10 cells on ampicillin plates
- Negative Control - TOP10 cells grown on ampcillin plates
