Linker oligos are recieved and don't need to be treated further. They can be used directly for the generation of the BioBricks.
storage and acceptor vectors are available.
PIF3 and PhyB were additionally ordered for synthesis (codon optimized). Not yet recieved.

generation of biobricks

We'll talk to Fabian. Apparently he has a nice protocol to generate acceptor vectors and transform E. coli sequentially in a 96 well plate.

testing of biobricks

testing of che-fusions

We're currently trying to establish an assay to test for the chemotactic behavour of E. coli. A first try with a "syringe test" failed. We'll redo the test and are looking for other possibilites. Maybe a swarm test?

  • tested biobricks: che-fusions
  • negative control: E. coli mutated for the accoding che-protein
  • positive control: wild type E. coli

testing of localicer-fusions

We are planning to use a fluorescence microscope in order to visualize the distribution of localizer-cyFP fusions within a single E. coli.

testing of couplers

We're planning to use the setup as for the testing of the localizers.

  • tested biobricks: localizer-PhyB and PIF3-cyFP, localizer-PIF3 and PhyB-cyFP

Images should look as in testing of localizer-fusions. Preliminary clarificaiton of the suitability of the approach are to be done.
