- Colony PCR (fw_ilvD_kivD , rev_pSB1C3_adhA)
- Annealing temperature: 65°C
- Bands not as expected (~3000 bp)
- Until now we didn't purified Inserts out of the gel if the backbone had another antibiotic resistence. We were using the PCR purification. But because it didn't worked out, we analyzed all our cut samples by gelelectrophorese. Thereby we discovered that the pSB1K3_alsS_ilvC_ilvD_kivD has an illigal restriction side.
Because of the integration of RBS's between all genes in the alsS_ilvC_ilvD_kivD-Plasmid, a restriction side between alsS and a RBS occurs.
New primers were ordered: rv_ilvC_alsS-new and fw_alsS_ilvC-new
- pSB1C3_alsS_ilvC_ilvD_kivD
- This week the new primers rv_ilvC_alsS-new and fw_alsS_ilvC-new arrived. We tried to remove the illegale restriction side.
- We tried different PCR amplifications to increase the chance to get a correct BioBrick. Therefore we amplified five parts for two combination possibilities in the Gibson Assembly:
- fw_kivD_pSB1C3, rv_alsS_pSB1C3 on pSB1C3_RFP
→ pSB1C3 with ~ 2200 bp - fw_pSB1C3_alsS, rv_ilvC_alsS-new on pSB1K3_alsS_ilvC_ilvD_kivD
→ alsS with ~ 1800 bp - rv_pSB1C3_kivD, fw_alsS_ilvC-new on pSB1K3_alsS_ilvC_ilvD_kivD
→ ilvC_ilvD_kivD with ~ 5200 bp - rv_kivD_ilvD, fw_alsS_ilvC-new on pSB1K3_alsS_ilvC_ilvD_kivD
→ ilvC_ilvD with ~ 3600 bp - fw_ilvD_kivD, rv_pSB1C3_kivD on pSB1K3_alsS_ilvC_ilvD_kivD
→ kivD with ~ 1800 bp
- Annealing temperature: 65 °C
- Bands as expected (see above)
- fw_kivD_pSB1C3, rv_alsS_pSB1C3 on pSB1C3_RFP
