Miniprep (using Omega Protocol)
1.1 Grow 1-5mL culture overnight in a 10mL-20mL culture tube.
1.2 Centrifuge at 2500xg for 5 minutes at room temperature. Decant or aspirate and discard the culture media. (Original protocol called for 10,000xg for 1 minute, but the speed and time above seemed to produce better results.)
1.2.1 Original protocol called for 10,000xg for 1 minute, but the speed and time above seemed to produce better results.\
1.3 Add 250uL of Solution I mixed with RNase A (pre-added). Vortex to mix thoroughly. Transfer the suspension into a new 1.5mL microcentrifuge tube.
