F2620 Expression Protocol
- Create Liquid Cultures in LB Media
- Dilute Back 1:500 in LB Media
- Grow up for an hour in warm room roller
- Split culture in two
- Add AHL to one culture to a final concentration of 1E-6M
- Grow up for 4 hours in warm room roller
- Spin Down, Decant, and Resuspend in PBS
- Measure absorbance at 600nm and red fluorescence level
See characterization data for BBa_F2620.
