*<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.

Modelling in this project has been important in defining the "Engineering constraints" of the project, and in particular, we have focused in quantifiying the [https://2009.igem.org/Team:Imperial_College_London/Temporal_Control temporal control] aspects of our system. This page provides an overview of the models we have implemented.

Starting the encapsulation process is related to diauxic growth of bacteria under the presence of two carbon sources.  2 models from literature have been discussed and implemented in this section. More information about each can be found in the extra tabs. After analysis of the models, we picked one of them as the best representation for our data. The sections below will provide a summary about each model, and at the end, discuss which one was picked and why. The diauxic growth phenomenon is tricky to understand, and the models we have chosen illustrate different approaches that groups have taken to explain what happens when bacteria switch to feeding from a primary carbon source to a secondary carbon source.

===Protein Production===

-
Based on the module 1 genetic circuit, a LacI-IPTG inducible promoter is responsible for kickstarting the production of the drug.

-
* In the absence of IPTG, LacI represses the production of the drug (Cellulase or PAH)
+
-
* When IPTG is introduced, the LacI repressing pathway is “de-repressed”, and some output protein is produced.

The modelling aims to provide an overview and better understanding of the M1 system’s function  by:
 
-
*Characterizing the system.
 
-
*Modeling to account for several factors that may reduce/hinder the production of  the protein drug such as:
 
-
**Lac promoter leakiness
 
-
**IPTG toxicity
 
-
**Stability of output protein
 
-
 
-
 
-
This module is an integral part of the design, as large-scale commercialization of the drug of interest depends on finding the optimal conditions for protein production. We implemented a system of differential equations, having made some assumptions and predictions about how the system will behave.

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:
