- Inoculate 200 mL of LB Broth with 50 μg/mL of KAN with the 5 mL overnight culture.
- Incubated culture for 2 hours at 37°C with 225 rpm.
- Add 205 μL of 1 M IPTG to the culture.
- Continue to incubate the culture at 37°C with 225 rpm for 4.5 hours.
- Split culture into four 50 mL falcon tubes and centrifuge at 3750 rpm for 30 mins.
