Preparation of Cell Extract
- Innoculated 45 ml of fresh overnight culture in 1 litre 2xYT medium
- Incubated at 37°C until O.D. 600 = 0.600
- Added 5 ml of 1 mM IPTG
- Incubated at 37°C
- O.D. 600 was 1.543 at 6pm
- Culture left at 37° in the incubator overnight
- Incubated new 100 ml culture overnight

Pilot Preparation of Vesicles
- Results:
The vesicles prepared the day before were looked at once again under a light microscope, with phase contrast. This time, vesicles were observed, with size range 2-43μm.

| Photos taken with a portable camera through the microscope eye-piece. Setup: 100x oil immersion objective, with phase contrast. | ||
- Preparations: The desiccation and suspension stages of the vesicle preparation protocol were carried out once again.
- One 100ml beaker was prepared with 125μl of DOPC in 50ml of mineral oil
- The suspension was sonicated for 30mins and left overnight in a 27°C incubator
- It was later found that the desiccator had no vacuum
