- kivD, alsS, ilvC, ilvD and backbone of pSB1C3
- We tried to redo the amplification of last week.
- Optimization of PCR conditions for coding sequence amplification
- Combinations of primers and templates as described before
- Annealing temperature gradients from 50°C to 58°C were tried
- Product amount was increased by lower annealing temperatures
- kivD, alsS, ilvC, ilvD and backbone of pSB1C3

- Optimization of PCR conditions for coding sequence amplification
- Combinations of primers and templates as described before
- Annealing temperature gradients from 50°C to 58°C were tried
- Product amount was increased by lower annealing temperatures
- For the annealing temperature we identified 54°C as optimal.
- For the elongation time 90 seconds worked better than 60 seconds.
- kivD, alsS, ilvC, ilvD
- With the optimized conditions the amplifications were tried again.
- PCR amplification with the optimized conditions and the primer combinations as described before
- PCR products were extracted out of the gel.
- Purfication of the gel slices
- Backbone of pSB1C3
- We aim to amplify it with Q5 polymerase
- PCR amplification (fw_kivD_pSB1C3, rv_alsS_pSB1C3)
- Elongation time: 90
- Bands not as expected (2,2 kb)
- PCR purification of backbone
- kivD, alsS, ilvC, ilvD
- This week we aim to prove if the constructs were right
- Restriction digestion with DpnI
- Bands (not) as expected (... bp)
- Gibson Assembly with kivD, alsS, ilvC and ilvD on pSB1C3
- Transformation with electrocompotetent cells
