Documentation:
Why are you doing this experiment? Name the parts which you extract.
ε5 was empty and the products from the cloning of 12.08.11 contain GFP-pbd too.
Name of the parts: GFP-pbd 4 4 4, GFP-pbd 4 1 3, GFP-pbd 6 6 8, GFP-pbd 4 2 2
Describe your results and mistakes and measure the DNA concentration with the Nanodrop and note the results.
| GFP-pbd 4 4 4: 164,1 ng/µl
GFP-pbd 4 1 3: 100,8 ng/µl GFP-pbd 6 6 8: 163,5 ng/µl GFP-pbd 4 2 2: 144,4 ng/µl |
How did you label your probes and where are they stored?
| Labelled GFP-pbd 4 4 4, GFP-pbd 4 1 3, GFP-pbd 6 6 8, GFP-pbd 4 2 2
stored in -20 until sequencing |

| Project Name:inducible promoter for pbd with cm-vector | |
For one reaction you need: For Mastermix: Number of samples+2extra
| 4μl | H2O | 20 | |
| 1μl | Buffer, NEB4 | 5 | |
| 1μl | BSA (10x) | 5 | |
| 0,5 μl | Enzym 1 | 2,5 | |
| 0,5 μl | Enzym 2 | 2,5 | |
| 3 μl | DNA |
10 μl total volume
Give 3 μl of DNA in an eppi and add 7μl of the mastermix.
Incubate for about 1h at 37°C.
Add 1 μl Loading dye buffer and load the gel.
Take a picture of the gel, print picture and label the lanes!

Experiment: Cloning | |
| Project Name: inducible Promoter for pbd with Cm-vector | |
Procedure
PCR tube:
total volume 20 μl
- add H2O (17 μl -X-Y-Z)
- add 2 μl Ligase Buffer 10x
- add Insert 1, Insert 2(when proceeding from 3A digestion use 2 μl of each)
- add Vector (20ng needed. When proceeding from 3A digestion use 2 μl)
- Add 1 μl T4-DNA Ligase
- Incubate 10-30 min at room temperature
- heat for 20 minutes at 80°C
- store at -20°C or directly proceed to transformation
