Project Name: GFP Pbd

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?

S14+P18+P28

S14+P19+P28

S14+P20+P28

Stored in PCR product box

(Name) Ruediger

Project Name:

GFP Pbd

Procedure


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

Vector (ratio 1:3 to insert)

Inserts (500ng)


Components Vector (μl) Insert1 (μl)
DNA (500ng) 5,6 12,5 4,7 3,5 3,8
BSA (100x) (5μl)
NEB4 Buffer (5μl)
Enzyme 1 (1μl) SpeI SpeI XbaI XbaI XbaI
Enzyme 2 (1μl) PstI PstI PstI PstI PstI
H2O (38 μl- DNA) 32,5 25,5 33,7 34,5 34,2
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
