Meeting
attendants: Jakob, Julia, Manuel, Rüdiger, Sandra, Theo, Tobi
time: 9:30 - 11:00
green light receptor
already done:
- CcaS: first quick change PCR removed the SpeI restriction site, EcoRI didn't work
- CcaR: first quick change PCR didn't work (EcoRI restriction site not removed), wrong PCR program
To-do:
- do the second quick change with the changed Ccas to remove the EcoRI restriction site
- repeat the quick change with the CcaR
- after the quick changes do a Gibson assembly with pcyA and ho1
- in parallel do 3A-assemblies to create the same construct as a backup plan
blue light receptor
already done:
- ordered new primers (the third pair)
- first primer pair had the overhang, second without overhang, third primer pair now without overhang and position shifted
To-do:
- try the gibson assembly again with the third primer pair
red light receptor
already done:
- 3A of pcyA and terminator sent for sequencing
- cph8 was sent for sequencing
- julia transformed the ompR promotor
To-do:
- add a Promotor-RBS to the pcyA-Terminator
- if the sequence is OK, amplify the part with the overhangs
- add terminator and Promotor-RBS
- do a miniprep of the ompR promotor
Lysis cassette
already done:
- 3A-assembly of the lysis casette
- 3A-assembly oth the GFP-PBD
- quick change PCR of the lysis casette (11 bases to insert the RBS)
To-do:
- do a miniprep from all three attempts
Precipitator
already done:
- waiting for godot
To-do:
- waiting for godot
other stuff
- start creating nice pictures to explain your subproject and write text to explain the pictures
- Sandra organized Freehand from the MPI, it is installed on both mac books
- give-aways: digital postcard, real postcard, fluorescent protein
- Tobi will ask at the financial department about the croud funding money
- Rüdiger will get us more media attention
- cooperation with other german teams: ask munich to do an appointment for a skype conforence about the light inducible promotors
- cooperation with Upsala: find an appointment for the skype talk

- Labeled as Jakob1 and Jakob2 in the fridge
2.Digest quickchange PCR with Dpn1
5µl Buffer NEB4
5µl BSA (10x)
2µl Dpn1
38µl DNA from quickchange (CcaS)
incubate at 37°C for 1,5 h
inactivate at 80°C for 20 min.
3 . T r a n s f o r m a t i o n
4.Picked some colonies
from transformation yesterday
- To-do: pick colonies, do Miniprep
blue light receptor
Gradient PCR of Lovtap with new primer
Investigators: Sandra
Primer:
- P38 (former name:P36) LOVdw
- P42 LOVtap up
DNA template:
- M35 (Lovtap)
PCR program:
- "Lovtap ohne Überhänge" with temperature gradient during the annealing step from 50°C-60°C. The elongation step and the final elongation step were extended.
"cold":50°C
"warm":60°C
Comments: PCR did not work again. We will try to do 3A-assembly.
