Protocol

  1. 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 for 45 min at 42°C.
  2. Heat-shock the cells for 120 secs, and place on ice again for 3-4 min.
  3. Add 1ml of LB broth and incubate the cells at 37°C for 1-15 hr in a water bath with gentle shaking.
  4. Plate out 100-200 µl/plate on LB (agar at 1.5%), containing the appropriate selection markers.
  5. Incubate plates overnight at 37°C.
