NAME OF YOUR EXPERIMENT
Investigators:NAME
Precipitator
Digestion this time the vector is dephosphorilated by antarctic phosphatase to avoid religation.

Experiment: new | |
Project Name:inducible promoter for pbd (iGEM standard) |
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) (Vector:Insert ratio 1:3 in following Ligation)
- 1 μl restriction enzymes (stored at iGEM’s, -20°C)
- heat for 1-2 hours 37°C (6 hours if time)
# add 5,6 μl antarctic phosphatase buffer and 1 μl antarctic phosphatase and incubate another hour
- heat for 20 minutes 80°C (inactivation of enzymes)
- keep at 4°C if you cannot continue
Measured DNA-concentration with Nanodrop to calculate the volume of DNA to do the digestion:
Sample Name | DNA concentration (μg/μl) |
GFP-pbd | 164 |
IPTG-promoter ε 5 | 217 |
psB1C3 | 58 |
Restriction enzymes you need to cut the vector, insert1 and insert 2:

Documentation:
Why are you doing this experiment? Where are the samples stored? Antibiotica resistance, vector used etc.
I want to be able to send the plastic binding domain to the registry and I want it to be expressible.
Stored in: “Minipreps, verdaut”-box Resistance: Cm |
