Preparation for Sanger Sequencing
Objective
- Clones grew well after overnight incubation, prepare clones for sanger sequencing. (a bit overgrown and most of the clones are blue in color)
Protocol
PCR amplification and preparation for sanger sequencing
- Add 12.5ul of 100ul of F and R primer and add 475ul sterile h2o to make 2.5uM primer mix
Content | Volume per reaction | MM |
DNA | Pick one colony per well | Do not add to MM |
H2O | 25 | 205 |
M13-21 F+R Primer (2.5uM each) | 8 | 65.6 |
2X Taq MM | 15 | 123 |
Total | 48 | 393.6 |
- Add 48ul MM to each colony
94C 10 min to break up the cells 94C 30 sec -> (94C for 30 sec, 60C for 30 sec, 72C for 1 min) x30 -> 72C 5 min ->15C forever

Results
- For some reason, no amplicons were formed, I suspect the ligation failed
Troubleshoot
- Either the polymerase or the pcr condition is not optimised, I will test both parameters with the control reactions to test the activity of the polymerase
Producing the Control PCR Product
Content | Volume per Reaction |
Control DNA template (100ng) | 1 |
M13 F+R (2.5uM each) | 8 |
Sterile water | 16 |
TagMM | 25 |
Total Volume | 50 |
