- psB1C3-alsS-ilvC-ilvD
- This week we wanted to identify positive colonies.
- Colony PCR (fw_alsS_ilvC, rv_kivD_ilvD)
- Annealing temperature: 65 °C
- Bands not as expected (~ 3450 bp)
- New try of the combination of the four CDS's with the pSB1C3 backbone.
- Gibson Assembly with kivD, alsS, ilvC and ilvD and pSB1C3
- Restriction digestion with DpnI
- Transformation with electrocompetent and chemocompetent cells
- Colony PCR (fw_alsS_ilvC, rv_kivD_ilvD)
- Annealing temperature: 65 °C
- Bands not as expected (~ 3450 bp)
- alsS, ilvC, ilvD, kivD and backbone of pSB1C3
- We started again back by zero to solve our problems.
- PCR amplification (as described before)
- We used pSB1C3-RFP instead of pSB1C3-CFP as template for backbone amplification
- Annealing temperature: 65 °C
- Bands as expected (~ 2200 bp)
- Restriction digestion with DpnI
- Gibson Assembly with alsS, ilvC, ilvD and kivD on pSB1C3
- Transformation with electrocompotetent cells
- Colony PCR (fw_alsS_ilvC, rv_kivD_ilvD)
- Annealing temperature: 65 °C
- Bands not as expected (~ 3450 bp)
- alsS, ilvC, ilvD, kivD and backbone pSB1K3
- This week we tried to begin from zero again with optimized conditions and new competent cells.
Therefor we prepared new plasmids from alsS, ilvC, ilvD, kivD and the backbone pSB1K3-RFP - PCR amplification
- Primer were used as described before
- pSB1K3-RFP was used as template for backbone amplification
- Annealing temperature: 53 °C
- Bands as expected for
alsS: about 1800 bp,
ilvC: about 1550 bp,
ilvD: about 1950 bp,
kivD: about 1700 bp,
but not for pSB1K3-RFP - PCR amplification with Q5 for pSB1K3-RFP
- Primer were used as described before
- Annealing temperature: 53 °C
- Bands as expected (~ 2200 bp)
- PCR products were purified
- Gibson Assembly with kivD, alsS, ilvC and ilvD on pSB1K3
- Restriction digestion with DpnI
- Aberation from protocol: Incubation for about 10 hours.
- Transformation with electrocompotetent cells
- Colony PCR (fw_ilvC_ilvD, rv_pSB1C3_kivD)
- Annealing temperature: 65 °C
- Bands as expected (~ 3600 bp)
- Colony PCR (fw_alsS_ilvC, rv_ilvD_ilvC)
- Annealing temperature: 65 °C
- Bands as expected (~ 3300 bp)
- Liquid cultures for a restriction digest were prepared.
- Plasmid isolation of pSB1K3-alsS-ilvC-ilvD-kivD
- Restriction digestion with NotI
- Bands as expected (backbone:~ 2200 bp and insert: ~ 7000 bp)
- adhA
- This week the Lactococcus lactis arrived. We tried to amplify it's adhA.
- PCR amplification of the adhA (rev-pBS1C3-adhA, fw-pSB1C3_adhA) and the Backbone out of psB1K3-RFP (rev-adhA_pSB1C3, fw-adhA-pSB1C3)
- Annealing temperature: 54 °C
- Bands as expected (~1200 bp for the adhA and ~ 2200 bp for the Backbone)
- PCR products were extracted out of the gel and purified.
- Gibson Assembly with adhA and pSB1K3
- Transformation with chemocompetent cells
- Colony PCR (rev-pBS1C3-adhArev-pBS1C3-adhA, fw-pSB1C3_adhA)
- Annealing temperature: 65°C
- Bands as expected (~ 1200 bp)
-
PCR:
- BioBrick Assembly:
- BioBrick Assembly (Suffix)
- Transformation with electrocompotetent cells
- Colony PCR (fw-pSB1C3-alsS, rv-ilvC-alsS)
- Annealing temperature: 65 °C
- Bands as expected (~ 1800 bp)
- Liquid cultures for a restriction digest were prepared.
