- Clone 1 : not the expected length
- Clone 2 – 4 : not digested
PCR of pGEMTeasy- FolC plasmid
23/07 – Yueying
In order to explain what was obtained with this digestion, we did a PCR with pGEMteasy plasmid as control.

PCR Results:
Expected size :
- plasmid + insert = 2 Kb
- plasmid = 230 pb
Our control shows a signal stripes at 2,5 Kb which is weird
2 and 4 signal stripes are as expected but quite wick.

PCR results :
Expected size :

- plasmid = 230pb
We can see a band at 2Kb, we obtain our plasmid with folC
Gel extraction of pGEMt easy- folC
We used the gel product purification protocol from Nucleospin Gel and PCR clean-up kit
