Tri-Stable Toggle Switch

Tristable Toggle Switch 2007.jpg
A trinary memory unit. A genetic circuit. A proof of concept. Here is the man-made architecture of the switch and the natural context of our parts.






Tri-Stable Model

Beta values.png
While Gardner et al created a mathematical model and a genetic switch in the Bistable paper, one was not used to design and improve upon the other. Here we extend our model to the Tristable system and discuss what certain parameters mean in terms of DNA and Proteins, Production, Repression, etc.





Testing Constructs

The dirty side of the switch. Testing constructs that will enable us to determine our constants in absolute terms and apply a mathematical basis to changes we make on the Tri-Stable Switch architecture.
