- Transferation of the starter culture into 1 L DYT medium in a 3 L flask resulting in an OD600= 0.2. Addition of 300 µL kanamycin.
- Incubation to an OD600= 0.6 at 180 rpm and 30°C.
- Incubation for 15 min. on ice.
- Induction of the proteinexpression with 0.8 mL of IPTG (stock conentration 1mM).
- Incubation of the cell suspension over night at 180 rpm at 16°C.
Protein Expression FsC

- Incubation at 180 repulsion per minute (rpm) at 30°C to an OD600= 4.
- Transferation of the starter culture into 1 L DYT medium in the 3 L flask with that results in an OD600= 0.2. Addition of 300 µL kanamycin.
- Incubation to an OD600= 0.6 at 180 rpm and 30°C.
- Incubation for 15 min. on ice.
