<!--
-
Large scale automation of production of protein of interest relies on being able to control when the manufacturing process begins. To do this, the initial design consisted of genetic constructs ([timers]). After implementing the simulations and obtaining design constraints, we realized that they were too complicated for the system. Instead, we chose to focus on autoinduction media, where we relied on primary and secondary consumption of sugars to control both the production of protein of interest and the encapsulation process.

Several factors must be taken into account in the system, and the goals of this model have been the following:

-
*Characterizing the LacI-IPTG system that is responsible for the production of the drug of interest.
+
-
*Modeling and accounting for several factors that may reduce/hinder the production of our output protein of interest such as:
+
-
**Lac promoter leakiness
+
-
**IPTG toxicity
+
-
**Stability of output protein
+
-
The protein production module is an integral part of our design, as large-scale commercialization of the product of interest depends on finding the optimal conditions for protein production and being able to tune and regulate the output.

*<b>Autoinduction:</b>

**This section is responsible for switching on the encapsulation process when glucose in the medium is used up by the cell culture.
 +
** The goal of the model is to quantify this switch point from a primary to a secondary carbon source and provide an understanding of the diauxie phenomenon.
 +
*<b>Protein Production:</b>
 +
** Production of the drug of interest is controlled by the input amount of IPTG in the system. Prior IPTG induction, production of the drug of interest is repressed by LacI.
 +
** The goal of the model is to account for factors that may enhance/reduce the output yield of our drug of interest.
 +
*<b>Drug Kinetics:</b>
 +
** The drugs we are producing (PAH, cellulase, opiorphin) are enzymes. In order to detect how much drug has been produced, an understanding of their enzymatic activity is required.
 +
** The goal of the model is to better understand the drugs of interest produced using the relationships derived by Michaelis-Menten.
 +
*<b>Genome Deletion:</b>
 +
** Genome deletion is induced by an increase in temperature. Different temperatures relate to different restriction enzyme concentrations, so here we explore the possible effects of temperature on cell death.
 +
** The goal of the model is to explore a possible relationship between live cells and dead cells over time at different culture temperatures.

Welcome to the Dry Lab!
The goal of the Dry Lab has been to support the Wet Lab by answering questions of interest. The primary function of the models is to instruct the data analysis once results are gathered from the lab. Conclusions from the models aim to provide the team with a functional understanding of the system as well as design considerations that should be addressed in the genetic constructs. We have implemented several models, explaining the behaviour of different parts of the system. Below is a summary:
