Building a Synchronized Oscillatory System

Modeling synchronized oscillations

Mathematical model of the construct

Since our bio bricked oscillatory system is based on the design published by Danino et al. in the paper [http://www.nature.com/nature/journal/v463/n7279/abs/nature08753.html “A synchronized quorum of genetic clocks”], our first model of the system is a reproduction of the mathematical model in the supplementary information accompanying the publication mentioned. In their simulations, Danino et al. used the following set of delay differential equations, which we used as base for our simulation tool written in matlab.

A: AiiA

I: LuxI

Hi: internal AHL

He: external AHL

The production of AiiA and LuxI depend on the internal AHL concentration.
