This page will help coordinate the experimental/computational work being undertaken to improve the evolutionary stability of engineered biological systems. Read here for more background.
Project Outline
- Evaluate and select several counter-selectable markers.
- Evaluate a method for reliable long-term cell growth in E.Coli. These include:
- Chemostat
- Batch dilutions
- Measure mutation rate of counter-selectable marker in long-term culture.
- Develop an codon optimization algorithm for specifying a new DNA seq for the counter-selectable marker
- Background research on the mechanisms by which cell spontaneiously mutate, the start of this can be found here.
- Synthesize counter-selectable marker with "stabilized" sequence
- Measure the mutation rate of the new marker.
