green light receptor
Testdigest with PvuI
Investigators:Julia
digested were Minipreps of Ligationreaction with CcaS.
The Enzym PvuI should cut into two fragments, one of 1666bp, the other 582 bp and vector at 2kb.
Protocol:
for Mastermix of 7 reactions:
30µl H2O
7µl NEB buffer 3
7µl BSA 10x
2µl PvuI
give 3µl of DNA sample to 7µl Mastermix, digest for one hour.
Add 1µl loading dye buffer(6x)a nd let the gel run.

| 0,5 μl | Enzym 2 | 2 | |
| 3 μl | DNA | 3 |
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.
Picture of the tesdigest: Expected sizes: L22+term(L21) ≈ 800 bp, L23+term(L21) ≈ 800 bp
L22a+b are correct
- To-do: send for sequencing

PCR-Mixture for one Reaction:
For a 50 µl reaction use
| 32,5µl | H20 | Name |
| 10µl | 5x Phusion Buffer | of Primer |
| 2.5µl | Primer fw | P18, P19, P20 |
| 2.5µl | Primer dw | P28 |
| 1µl | dNTPs | of Template DNA |
| 1µl | DNA-Template | PCR product of P1,P3,S14 from yesterday |
| 0.5 µl | Phusion (add in the end) |
What program do you use?
One set of probes was prepared and then split into 3 tubes each to test them at Annealingtemperatures 44C, 52C and 60C for the first 10 cycles. Then Annealingtemperature 60C for 25 cycles
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?

Procedure
- add H2O (38μl-DNA )
- 5 μl NEB4 buffer (stored at iGEM’s, -20°C)
- 5 μl 10x BSA (used 1:10 diluted sample stored at iGEM’s, -20°C)
- DNA (500 ng)
- 1 μl restriction enzymes (stored at iGEM’s, -20°C)
- heat for 1-2 hours 37°C (6 hours if time)
- heat for 20 minutes 80°C (inactivation of enzymes)
- keep at 4°C if you cannot continue
Vector (ratio 1:3 to insert)

| In total 50 μl | |||||
Measured DNA-concentration with Nanodrop to calculate the volume of DNA to do the digestion:
| Sample | DNA concentration (μg/μl) |
| S14+P20+P28 (short:20) | 132 |
| S14+P19+P28 (short 19) | 145 |
| S14+P18+P28 (short 18) | 107 |
| S39 | 90 |
| S43 | 40 |
Documentation:
Why are you doing this experiment? Where are the samples stored? Name of samples, antibiotica resistance, vector used etc.
| Want to ligate GFPpbd (3 different versions P18/19/20) into PR vectors (one with strong Promotor strong RBS, one with middle Promotor, middle RBS)
CM Resistance Mistake: took 100x BSA instead of 10X |
