Parts Statuses

  • Pfet3, Panb1, lacZ: PCR was not successful after many tries. For Pfet3, new primers were designed but there was no time left to complete this part.
  • Tadh1: Tadh1 has been successfully amplified and ligation in pGEM vectors is under way.
  • pRS313, pRS315, pRS316: The shuttle plasmids are available and digested.
  • Padh1, Psuc2, rox1, mig1, luciferase, mPR Danio rerio, mPR Xenopus laevis: These parts are all available and digested. The ligation in both pSB1C3 and our pRS shuttle plasmids was so far not successful.

Identified Problems

  • PCR problems: Some PCRs yielded only products in very low concentrations. Some primers also amplified multiple fragments. New primers partially solved these troubles.
  • Transformation efficiency: The first batch of chemocompetent had a very low transformation efficiency. Newly prepared cells showed much better efficiency.
  • Ligation problems: Due to our assembly strategy (only XbaI/SpeI digestion) we had troubles with very low efficiency of insert ligation. Further complication is that the insert can be ligated in the wrong direction. This assembly was necessary because the shuttle plasmids feature only the XbaI/SpeI pair in its multiple cloning site.
    These problems are the main point why assembly and part submission failed.
