2. Thaw competent cells on ice
3. Aliquot 50-100 μL of cells into two pre-chilled 15 mL culture tubes (one for the control, one for the actual transformation)
4. Add 1-2 μL of plasmid and swirl gently
5. Incubate tubes on ice for 30 minutes
6. Heat pulse tubes in 37°C degree water fro 30-40 seconds
7. Incubate tubes on ice for 2 minutes
8. Add 500 μL of preheated SOC broth to each tube and incubate for an hour at 37°C with shaking
9. Spread 100 μL of each culture on a LB agar plate containing the appropriate antibiotic(s) and incubate overnight at 37°C
10. Alternatively, take 50ml tube filled with LB-media that contains the appropriate antibiotic and incubate overnight with shaking at 37°C.
