Riboregulator
digesting test of e0040->pSB3k3
- single digesting test of e0040->pSB3k3-1 and e0040->pSB3k3-2 with EcoR1
- double digesting test 0f e0040->pSB3k3-1 and e0040->pSB3k3-2 with EcoR1 and Pst1, respectively
- for 2 hours
electrophorese the product of digsting test
- from left to right:

digesting R0040 and J23078(crRNA) for ligation
- digesting R0040 with Spe1 and Pst1
- digesting J23078 with Pst1 and Xba1
- for 15 hours
oriT Knock Out
- By Xu Anting
- Use chromosome extraction product as template to do PCR, with Taq or Pfu added.
- Result: In Taq PCR all 6 pairs of primers show bright bands at 500 bp, while none is shown in Pfu PCR.
- Conclusion: finally I got oriT up- and downstream fragments of 500 bp with potential site mutations caused by Taq's relatively low fidelity. I intend to use these products as template to do further PCR and get oriT-deleted fragments of 1200 bp.
