- Overnight culture in 10 mL LB, fresh colony.
- Dilute 1:100 in 500 mL LB, grow to OD .4-.5, takes between 2-3 hours. Shake on ice to stop the growth before spin.
- Spin in prechilled bottle at 3500rpm for 15min.
- Do the rest in the cold room or on ice bucket: resuspend in 25-50mL ICE-COLD TSS with prechilled pippette.
