Design Notes

We are still in the process of optimizing this device, the following considerations are undergoing testing:

- tagRFP was taken from an expression vector, did it lose 5' components essential for high expression?

- Can we reduce the frequency of spontaneous loss of function mutations in sacB through protein fusion with kanR?

- Is the kanR RBS too strong for the desired resolution of susceptibility? Can a weakened RBS increase the range of the selection?

- Similarly, is the RBS of K322921 too weak? Are we not getting enough translation of sacB to kill the population?

Source

tagRFP came from Evrogen sacB and kanR came from the registry
