Design Notes

Sequence was PCR'd from T. Maritima. An additional TGA stop site was added.


Helpful Tips

TD-PCR

  • Forward Primer
    • 5'CTT CTA GAT GGA ATT TCT GAA AAG ATC
  • Backward Primer
    • 5'CTA CTA GTA TCA TCA GAA CTT TAG AAG AAT CA
  • TD-PCR amplification temperatures:

Notes

  • Primers
    • The primers used and noted above contain a SpeI site downstream and a Xbal site upstream for "easy" ligation into a biobrick plasmid.
  • Polymerase that was used was KapaHiFi (Engineered variant of of Taq)
    • Required to increase the [] of MgCl2.
    • After amplification at the specified TD-PCR program there was no unexpected bands


Suggestions

  • Primers
    • For better enzymatic digestion of SpeI and Xbal it was suggested to extend the primers beyond the recognition sequence by a few base pairs to allow something for the enzymes get a "grip-on"
      • As long as 3' end of primer is complementary there should be no issues with primer annealing.
    • TD-PCR was done to ensure we had product to extract and subject to another round of PCR to optimize , however due to lack of non-specific products the PCR protocol was never optimized.
