Kill Switch

The Kill Switch mechanism is the most complex and ambitious aspect of our project on the protein level. The DNA constructs are very large and even exceed the Part Registry´s frame (Fig. 1). For details on its design and function see here. We were very excited to start experimenting with the killswitch moss. However, when we opened the redlight filter foil, we found none of the allegedly transgenic moss lines had survived. There is a variety of possible reasons for this outcome that need to be discussed in order to improve our approach.

  • in bakkis nicht exprimiert [codon usage]
  • promotor zu stark [bild vgl prom stärken]
  • konstrukt zu groß für trafo [homologe regionen??]
  • filter nicht optimal [bild filter, ingmar @ blaulicht bench?]
