- | <br/>Transformation (D-Day):
| + | |
- | | + | |
- | <br/>1. Pick up a nice big colony and drop it in 2 ml of completed MC (1x)(see sub1).
| + | |
- | <br/>2. Grow at 37 °C for 5 hours (more if culture is not really turbid).
| + | |
- | <br/>3. Mix 400 µl of culture with DNA* in fresh tube (i.e. 15 ml tubes loosely closed – aeration) (*usually 1 µl. Then 10 µl of Quiagen plasmid miniprep or <1 µl of chromosal prep)
| + | |
- | <br/>4. Grow for an additional 2 hours at 37 °C.
| + | |
- | <br/>5. Plate all on selective antibiotic plates, and incubates at 37°C o/n.
