15/04/28
GXL-PCR
Used primers:
Promotor (plac): IC1 + IC2
csgA: IC3 + IC4
RBS + mCherry: IC5 + IC6
Backbone: IC7 + IC8
15/05/07
Resuspending of speedvaced gel extracted plac, mCherry, Curly
high values (100g/µl-250ng/µl) but weird curves
CPEC
15/05/08
Gel of CEPC reaction
No clear band visible, with a lot of imagination there is a band, which would be right in size -> transform anyway
Transformation of CEPC Curly
--> next day: colonies are visible
15/06/08
Overnightcultures
W3110 Δcsagα cells in 1 mL LB-Media
eCsgAα-Cells in 1 mL LB-Cm-Media
15/06/09
Overdayculture
W3110 Δcsagα + pC1 in 3 mL LB-Cm-Media (1% Glucose)
Platereader experiment
1. Add 30 µL overnight culture (probe B1 in the 96-well-plate)
2. After 2 h: induction with IPTG (probe B2 in the 96-well-plate)
3. After 2 h: fluorescence measurement with the plate reader
4. Non fluorescent cells (Control)
5. culture 4h after induction
6. culture 4h after induction 1:10 diluted

Overday culture (W3110 DcsagA cells)
- 50 mL SOB-Medium
- Add 50 µL overnight culture
- Incubate 3 h at 30°C, then 1 h at 37°C
- OD = 0,46
- Preparation of electrocompetent cells
Electrocompetent cells
W3110 Δcsagα cells
Transformation
pC1 (constructed Curli-Plasmid)and iGEM (Curli, Lyon, 2014) plasmid (p70) into W3110 Δcsagα cells --> repetition because not many colonies (pC1) and not successful (p70)
15/06/10
Transformation
p70 in DH5α-Cells and pC1 in W3110-Cells, repetition of the streak out for the W3110 ΔcsgA cells (no colony picking possible)
15/06/11
Colony-PCR
Overnightcultures
W3110_pC1,W3110Δ_pC1,p70 in LB-Cm-Media
15/06/12
Platereader experiment
- Preparation of a day culture from overnight culture
- After 2h, prepared 96 well plate with different dillution of IPTG (10µL) (0mM, 0.01mM, 0.1mM, 0.5mM, 1mM, 10mM) to each strain (90µL) (DH5α, W3110 WT, W3110 ΔcsgA)
- Read out by fluorescence Photometer
