Meeting
attendants: Jakob, Julia, Manuel, Rüdiger, Sandra, Sophie, Theo
Time: 9:00 - 10:00
green light receptor
already done:
- Ccas some colonies (check if positive)
- CcaR still doesn't work
To-do:
- cph8 still won't work, we should ask to get the original sequence
blue light receptor
already done:
- receptor and NOT-Gate assembly
To-do:
- add Promotor-RBS and terminator
red light receptor
already done:
- Promotor-RBS-ho1-terminator ready
- Promotor-RBS-pcyA-terminator ready
To-do:
- receptor still doesn't work (not possible to amplify via a PCR)
Lysis cassette
already done:
- quick change with the 11 bases didn't work
- did a 3A assembly with the single parts
To-do:
Precipitator
already done:
- finally the genes arrived
- GST from the bioss toolkit can't be amplified from the supported vector, Rüdiger should do a positive control next time, if it still doesn't work he should get new primer pairs
To-do:
- PBD + inducible promotor
other stuff
- Hauke Busch recommended CellDesigner to Rüdiger to do the modelling, Rüdiger will download it and try to install it
- modelling should be done for the precipitator, escpecially the Ni-Histidin-binding and for the plastic binding domain, maybe also the GST-Tag affinity
- Tobi will organize moving the stuff out of the lab after the wiki freeze
- Sandra will ask for the appointment to talk at the MPI
green light receptor
NAME OF YOUR EXPERIMENT
Investigators:NAME
blue light receptor
Sandra, Sophie: primer design for NOT-gate to get NEH I restriction sites inside instead of Spe I. We can not cut with Spe because our trp-promoter contains Spe restriction sites.
red light receptor
NAME OF YOUR EXPERIMENT
Investigators:NAME
Lysis cassette

Digestion
Name:Rüdiger | Date:19.08. |
Continue from Date 19.08. Name Sophie, Sandra
Experiment Miniprep | |
Project Name:Precipitator |
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)
- 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) |
M61a | 335 |
M61b | 300 |
M62a | 267 |
M62b | 263 |
M63a | 447 |
M63b | 412 |
Restriction enzymes you need to cut the vector, insert1 and insert 2:

digested with EcoRI and PstI.
Gel extraction kit
Investigators: Theo
DNA fragments of the digestion( see above) were excised from the gel.
Ligation
Investigators: Rüdiger
Trying to ligate the precipitator (excised from the gel) in the pSB1C3 vector. Ratio of ligation: 1:3
