1. Fill appropriate number of 96-well plates with 110 µL LB-Amp.

2. Use 96-pin sterile replicators to replicate each original into 2 new plates, A and B.

3. Make sure rows and columns are aligned correctly (this is NOT obvious!).

4. Grow o/n (~ 20 hrs) at 37 °C in humid chamber (wet paper towels in container covered loosely).
