Week 4

  • One more try to get Fiu protein on pSB1A3 backbone. NovaBlue transformed with ligation products of pSB1A3 and Fiu.
  • Grew colonies for FhuA and OsmE midi preps.
  • Carried out midi preps for FhuA and OsmE ( [FhuA]=378.9 ng/ul, [OsmE]=113.2 ng/ul).
  • Transformed Nova Blue with biobrick part BBa_B0014 (double terminator)
  • Culture colonies of BBa_B0014 transformants to get ready for mini prep.
  • PCR FhuA and GFP for assembling together a quick and dirty fusion to be ready prior to BioScaffold arrival.
  • Carried out colony growth (agar & liquid) for the AraC promoter (2 parts BBa_R0080 (lacking O2 region) and BBa_R0081 (the O2 region).
  • Miniprepped DNA from cultures of BBa_R0080 and R0081.
  • Attempted a 2-way ligation and of the BBa_R0080 and R0081 parts. The final product should be a 2-component biobrick on a plasmid in 5'-R0081-R0080-3' direction which can be transformed into cells.
  • R0081 part was purified by gel extraction after being treated by double digest. R0080 and R0081 were ligated together and used to transform NovaBlue cells.
  • First attempt to make the AraC promoter from the two parts failed.
  • Fiu still not being ligated on ANY backbone.
