pSB1A3-Receiver-Colicin cloning
- Digestion of pSB1A3 with XbaI and SpeI from cloning cultures of last week. We used these cultures because the bande where easier to distinguish. !!!
- 2008-09-18 UPDATE: the different bands were probably from the religated pSB1A3 plasmid, which cannot be cutted with XbaI and SpeI. -> No cutted pSB1A3 backbone
- Gelextraction of pSB1A3: 0.7 % Agarose, 1 h, 135 V
- Gelextraction of pSB1A3: QIAquick Gel Extraction (Qiagen), eluted in 30 µl H2O

Colicin activity test
- 9 am: One E9 - M9 culture, one E1 - M9 culture and one E1 - LB culture were stressed with 10 µl of 0.1 mg/ml Mytomycin C
- 4 pm: The colicin E1 LB cultures were thrown away, because the grew well in M9. The MG1655 and colicin cultures were sonicated in a ultrasonic bath three time for 15 seconds. After sonication cell extract was observed under microscope -> lot of dead cells -> succesfull lysis.
- Overnight-Activity-Assay:
- lysed cells were centrifuged for 15 min at 400 rpm. The supernatants were transferd to new falcons and were used for a colicin activity test.
- well plate scheme:
3:1 -> 3 ml M9 media + 1 ml supernatant + 200 µl reference promotor cells (I20260) 1:1 -> 2 ml M9 media + 2 ml supernatant + 200 µl reference promotor cells (I20260) 1:3 -> 1 ml M9 media + 3 ml supernatant + 200 µl reference promotor cells (I20260)
- ON-measurement for 14 h at 37 °C in Tecan well plate reader

pSB1A3-Receiver-Colicin cloning
- New ligation because controll gel didn't show any bands for pSB1A3 -> probably a too low concentration: : 1 h 40 min RT, 15 min 65 °C
10 µl Receiver DNA 6 µl Vector DNA pSB1A3 (sapped, from last week) 2 µl Buffer T4 DNA Ligase (Fermentas) 2 µl T4 DNA Ligase (Fermentas) ----- 20 µl
- Transformation of ligation (Tuesday 2008-09-11) into E. coli TOP 10 cells: 5 µl per 50 µl E. coli BL21 cells
- start thawing 50 µl competent E. coli TOP 10 cells on crushed ice - add 5 µl ligation - incubate on ice for 20 minutes - heat shock at 42 °C for 45 sec - incubate 2 min on ice - add 200 µl preheated LB media - incubate at 37 °C for 1 h, 300 rpm - Plate 200 µl on preheated LB-Amp plate - incubate overnight at 37 °C
- Controllgel of PCR: 1% Agarose, 30 min, 135 V
HisTag cloning of Colicins for purification
- Transformation of ColE1 and ColE9 into BL21 cells: 5 µl per 50 µl E. coli BL21 cells
- start thawing 50 µl competent E. coli BL21 cells on crushed ice - add 5 µl ligation - incubate on ice for 20 minutes - heat shock at 42 °C for 45 sec - incubate 2 min on ice - add 200 µl preheated LB media - incubate at 37 °C for 1 h, 300 rpm - Plate 200 µl on preheated LB-Amp plate - incubate overnight at 37 °C
Colicin activity test

pSB1A3-Receiver-Colicin cloning
- Transformation results: we picked and plated 8 colonies of each transformation on LB-Ampicilin plates and in addition we inocculated liquid cultures.
HisTag cloning of Colicins for purification
- Transformation results: We plated our transformation on LB-Kanamycin because BL21 cells contain a helper plasmid which has an Kanamycin resistance. But pQE-30 plasmids have an Ampicilin resistance. Because of that we transderd colonies from an bacteria lawn to Ampicilin/Kanamycin plates.
