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

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)

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

Transformation
pC3 into W3110Δ, W3110 RH, W3110 RHΔ --> not successful
Transformation
pC3 into W3110 --> not successful
preparation of Cryo-Stocks
plate W3110 and W3110Δ on plates
15/07/07
Transformation
pC3 and pUC19 (as control) into W3110Δ, W3110 RH, W3110 RHΔ
Transformation
pC3 and pUC19 into W3110, DH5α
Overnight cultures
W3110, W3110Δ and DH5α + pC3 for cryo stock
15/07/08
Transformation did work (except for the DH5α strains, probably mistake while pipetting or something), prepared new plate with cells, because the growth was to compact
Cryo stocks
