2. Cells or colonies were picked up from the source with a toothpick under sterile conditions.

3. 5ml of LB medium, supplemented with the required antibiotic, were inoculated with the toothpick.

4. Tubes were incubated at 37^oC in a rotary incubator at 200rpm over night.

Protein Expression Optimization Protocol

SDS-PAGE and Western Blotting

1. 50µl of an overnight culture was used to inoculate 5ml of fresh LB containing the appropriate antibiotics and left to grow at 37^oC in a shaking incubator.

2. Once the OD₆₀₀=0.6-0.8, 1mM of IPTG was added to the culture and left to grow for a further 3 hours.

3. 1ml of each culture was taken and spun down in a microcentrifuge for 3 minutes.

4. Meanwhile, 950µl of 2x Laemmli sample buffer was added to 50µl of B-mercaptoethanol.

5. The supernatant was discarded from the samples and the pellet resuspended in 200µl of the above solution.

6. The samples were then boiled at 90^oC for 10 minutes.

7. Afterwards, they were spun down for 1 minute in a microcentrifuge.

8. At this stage, the samples could be stored at -20^oC or ran on a gel immediately.

9. Two gradient gels consisting of a 12% separating gel and a stacking gel were prepared and the samples ran at 100V until proteins reach end of the stacking gel at which point the voltage was increased to 200V for 20 minutes.

10. One gel was stained using Instant Blue and the other was used to transfer the proteins onto a membrane.

11. After the proteins had been transferred onto the membrane, the membrane was blocked in 5% Marvel milk overnight at 4^oC.

12. The next day, the membrane was washed 3 times in 1xTBST buffer and then suspended in 10ml of 1xTBS buffer to which the primary anti-His antibody was added and left for one hour. The protein ladder was cut off before adding the primary antibody.

13. The membrane was then washed 3 times in 1xTBST buffer for 5 minutes and then suspended in 10ml of 1xTBS buffer, to which the secondary antibody was added and left for one hour.

14. The membrane was then washed in 3x10ml 1xTBST buffer for 5 minutes.

15. The blot was then soaked in developing solution for 5 minutes before being wrapped in a plastic cover aligned with the protein ladder that was cut off at step 12.

Once in the developing room, the film was exposed to the blot for 30 seconds, 2 minutes and 5 minutes and then placed in the film developer.
