iGEM 2006 Useful Information

The University of Calgary 2006 iGEM team is working on the following project. A petri plate is inhabited by two strains of genetically engineered E. coli bacteria. The first strain---the Senders---have been engineered to emit two chemical signals into the plate environment: Aspartate and Acyl Homoserine Lactone (AHSL). The senders themselves are activated by light. The second strain---the Receivers---have been designed to respond to each of these signals in a different way. The Receivers express Green Fluorescent Protein in the vicinity of AHSL. The Receivers also move towards areas of greater Aspartate concentration. The same bacteria also decrease Aspartate levels where they are present, as this is a nutrient and constitutes the reason for why they are attracted to it in the first place. Our goal is to make the Senders and Receivers create interesting behaviour dynamics visualized by fluorescent patterns.
