  • Ryan - minipreps & digests
  • Ryan - PCR & Dig/Lig (promoter insert trial #2)


Minipreps

  • Use Sigma GenElute; elute with 75 μL elution solution
  • BraR/MRV colonies - picked 4 additional colonies from original cloning plate
  • Cut w/ E/X
  1. Bra/MRV 3
  2. Bra/MRV 4
  3. Bra/MRV 5
  4. Bra/MRV 6
  • promoter/Regulator/MRV colonies
  • Cut w/ KpnI/EcoRI - BbsI drop-in of promoter destroys KpnI site; empty vector will produce 2 bands, successful clones will be linearized (1 cut)
  1. pAub/AubR/MRV
  2. pBja/BjaR/MRV
  3. pRpa/RpaR/MRV


Reagent Volume Expected:
1-4. Bra/MRV = ~3200, 776
Empty MRV E/X = ~3200
5. pAub/AubR/MRV = 4240
6. pBja/BjaR/MRV = 4099
7. pRpa/RpaR/MRV = 4116
Empty vector = ~4000, 971 		Hover name
15 μL/lane; 1% agarose; Ladder
DNA(plasmid) 3.0 μL
10X buffer 1.5
enzyme 1 1.0
enzyme 2 1.0
dH2O 8.5
  15 μL --> 37°C/ ~15 min.


  • Measure [DNA]
Sample OD 260 260/280 ng/μL
BraR/MRV #5 0.465 1.913 465.4


Conclusions

  • BraR/MRV - Success! Keep colony 5 (lane 3)
  • promter/Reg/MRV - none worked. Try the assembly again with PCR-amplified promoter inserts


Ryan - PCR & Dig/Lig (promoter insert trial #2)

Ryan - Receiver plasmids, assembly - REVISED STRATEGY (PCR promoters)

  • Stage 1 - insert Regulator ORFS
    • Phusion PCR-amplify ORFs (add 5'-E, 3'-X cut sites)
    • Insert ORF(E/X) into Vector (E/X). see Vector plasmid map
  • Stage 2 - insert Promoters
    • PCR-amplify promoter inserts (same primers as Stage 1)
    • Cut & dephos promoters with E/X
    • Insert promoters(E/X) into Vector/Regulator (BbsI) via Lig/Dig cycling


Assemblies

  1. pAub/AubR/MRV: pAub(E/Xdp)/153 + AubR/MRV(BbsI)/4087
  2. pBja/BjaR/MRV: pBja(E/Xdp)/122 + BjaR/MRV(BbsI)/3977
  3. pBra/BraR/MRV: pBra(E/Xdp)/214 + BraR/MRV(BbsI)/3977
  4. pRpa/RpaR/MRV: pRpa(E/Xdp)/136 + RpaR/MRV(BbsI)/3980
