CMV PCR (Sabine)
-PCR with primer for the CMV promotor; as DNA template the CMV+RLuc construct from the Ljubljana group (isolated from the parts collection 2007) was used.
For a 50 µl reaction:
40,4 µl H2O
5 µl buffer (10x)
1,5 µl FWD Primer (15pmol)(
1,5 µl REV Primer (15pmol)
1 µl dNTP (10mM)
0,1 µl DNA template
0,5 µl Pfu Polymerase
The settings for the PCR machine are the following:
1. T=94°C 00:02:00
2. T=94°C 00:00:30
3. T=62°C 00:00:30
4. T=72°C 00:01:00
5. GOTO 2 REP 29
6. T=72°C 00:10:00
7. HOLD 6°C
No product was received.

1) Origami with NIP and fluorophor for the binding measurement
We had to produce some new origami for our next binding measurements.
- Origami with NIP and fluorophor
- Origami only with fluorophor (without NIP); negative control
see at the protocol from 07-24-2008
2) Origami for the Calciummeasurement
- Origami without NIP (negative control)
see at the protocol from 07-24-2008
To increase the concentration of origami we also made to probes with the double amount
ingredients of the protocol from 07.24.2008

3) Master cycler
The origamis were produced in the mastercycler as explained before.
4) Purification of the DNA Origami
Was done as before
5) Digestion of CMV+Rluc (Sabine)
Digestion with EcoRV und FspI (3h at 37°C)
- 5µl plasmid
- 10µl H2O
- 0,5µl enzyme
- 2,5µl buffer (2)
- 0,5µl BSA

6) CMV PCR (Sabine)
-the same PCR with different annealing temperatures using a gradient between 58°C and 62°C (optimal annealing temperature: 62°C)
-again, no products were gained
Sep. 15th 2008
CMV-PCR (Sabine)
-another effort to gain the CMV-Promotor via PCR, this time with different polymerases: Taq Polymerase and a Mix.
-one approach with the complete plasmid and one with the digested plasmid (see digestion of CMV+Rluc)
-products in the approach with taq polymerase as well as in the approach with the Mix. 3 bands from each approach were cut out
Sep. 16th 2008
