2. Add 2μl plasmid DNA to thawed cells and mix by flicking the side of the tube.
3. Incubate on ice for 20 minutes.
4. Pre-warm antibiotic plates in 37⁰C incubator.
5. Heat shock for 1 min 15 sec at 42⁰C.
6. Place on Ice for 2 minutes.
7. Add 500ul 2XTY (or SOC) medium (kept at room temp) to each tube (medium with NO antibiotic).
8. Shake the tubes at 37⁰C for 1 hour on a shaking incubator.
9. Spread 100μl of each transformation tube on appropriate antibiotic plates.
-In addition, you can: Take 1μL of TOP10 and add 99μL of growth buffer, plate it. Spin remainder for 1 min at 13000, discard supernatant, re-suspend in 100μL of growth buffer
10. Incubate at 37⁰C overnight.
