green light receptor

second quickchange of CcaS

Investigators:Julia

PCR-Mixture for one Reaction:

For a 50 µl reaction use

What program do you use?

After PCR: Digestion with DpnI in order to get of the old plasmids :

5 µl NEB buffer 4

5 µl BSA (10x)

2 µl DpnI

38 µl of PCR Product

Incubation for 1,5h, deactivation at 80°C  for 20 min.

Transformation with 10 µl of the digested PCR product. Cells were plated out on Kanamycin plates( at 23:00 o’clock ).

Sequencing

Investigators: Sandra

The sequencing showed that the 3A-assembly did not work. We will send the LovTap PCR product to get sequenced. May be the PCR did not work.

PCR

Investigators: Sandra

PCR of Not-Gate.

P 74:

• actgcagcggccgctgctagca

P 24:

• tatgaattcgcggccgcttctag

PCR product was loaded onto a gel. Expected lane: 900bp
PCR worked and we got Not-Gate with NEHI and PstI.

Cloning

Investigators: Sophie

new 3A assembly with Sandra's NOT-gate-PCR-product, our LOV-Tap-pcr-product (both mutated with NEH1 restriction sites) and an amp-vector
The digested samples were loaded to a gel. They showed clear bands in the right size. Only the band of the vector was not intense enough, so the vector has to be digested again.

Procedure

1. take cells from -80°C freezer and put them on ice! (every eppi contains about 400 μl cells)
2. thaw cells on ice 20 minutes
3. pipette 50 μl cells and 2 μl DNA into eppi still on ice!
4. Incubate for 30 minutes on ice
5. Heat at 42°C for 60 sec
6. Incubate on ice for 5 minutes
7. Add 200 μl LB Broth
8. Incubate for 2 hours at 37°C (cells with lysis cassette at 30°C!!)
9. Plate 50 μl and 200μl on two different LB/Agar plates with appropriate antibiotic resistance

Documentation:

Why are you doing this experiment? Name of the sample? Where are they stored? Name the vector with inserts, antibiotika resistance etc.

Transformation

Investigators: Rüdiger, Sandra

Transformation of:
61 a,b
62 a,b
63 a,b.

Vector:pSB1C3

Incubation over night.

Cloning for GFP-pbd with IPTG-inucible promoter

Investigator: Sophie
as cloning from 18.08.11 did not work I try it again with longer digestion times.

PCR

PCR-Mixture for one Reaction:

For a 50 µl reaction use

What program do you use?

Anneal Gradient from 61-72°c, 15sec.

To confirm the PCR-Product has the correct size, load 2 µl of the sample onto an agarose-gel.

How did you label the PCR-Product, where is it stored and what do you do next?
