Transformation of E. coli
Materials required
- Appropriate E. coli strains (200 µl)
- Appropriate vector DNA
- Heat block
- Bucket of ice
- Pipettes
- Eppendorf tubes
- 1.5% agar plate containing appropriate antibiotics
Procedures
- Thaw a 200 µl aliquot of the desired strain of E. coli and add the transforming DNA (10 ng of vector DNA in 10 µl). # Incubate on ice for 30 minutes.
- Heat-shock the cells for 120 seconds at 42°C, and place on ice again for 3-4 minutes.
- Add 1 ml of LB broth and incubate the cells at 37°C for 1-15 hr in a water bath with gentle shaking.
- Plate 200 µl of transformed E. coli onto 1.5% agar plate containing the appropriate selection markers.
- Incubate the plates overnight at 37°C.
