Morning meeting
We discussed the project proceedings.

- IgG protease
- Superoxidase dismutase (SOD)

- bFGF
- Primers for not-yet amplified genes should be redesigned to include the complete Assembly standard 25 prefix and suffix.

- BL21(DE3) was chosen as our strain for IPTG-induced protein expression from pEX vector.

Expression of SOD and yCCS from pEX expression vector
Continued from 29/6
We realized that Top10 and DH5alpha are not suitable for IPTG-induced protein expression. SOD and yCCS expression was therefore not proceeded from ON cultures. Glycerol stocks were prepared from ON culture and pEX.SOD and pEX.yCCS plasmids were prepared.
DNA concentrations
| Sample | DNA conc (ng/ul) | A(260)/A(280) |
| pEX.SOD | 18.15 | 1.98 |
| pEX.yCCS | 20.55 | 1.97 |
Preparation of competent BL21(DE3) cells
- 5 ml LB was inoculated with BL21(DE3) cells and grown ON in 37°C, 250 rpm.
