Welcome to the Stanford team Wiki for iGEM 2010
Stanford iGEM is a student-run, faculty-directed research group at Stanford University. The objective of our interdisciplinary group is to design and build novel engineered biological systems using standardized DNA-based parts to submit to the iGEM (International Genetically Engineered Machines) competition, held annually at MIT. Our research draws from the principles of synthetic biology, an emerging interdisciplinary and multidisciplinary area that involves the design and construction of biological systems. Here is our team for the 2010 competition and our [http://igem.stanford.edu/ page] on the Stanford University Website.

Our Project: EscheRatio Coli
The field of synthetic biology is in the process of a rapid expansion. As more and more researchers join the burgeoning discipline, they will need new biological tools. This year our team created a new type of tool for the synthetic biologist's toolkit: a system to allow E. coli to sense the ratio of two different chemicals in its environment and produce a protein output based on that ratio. Our new sensors will allow synthetic biologists to explore novel application areas beyond the limits of current sensors. While designing these new tools, we asked ourselves critical design questions. We invite you to follow along in our decision process.
Why Ratios?
We've implemented two different ratio sensor designs:
- an sRNA-based sensor that reports the relationship between the present ratio of the chemicals and a single desired ratio via the presence or absence of signal
- a kinase-phosphatase sensor that reports the exact ratio via the intensity of the signal
Why Ratios?
Ratios run the biological world, from the complex functions of the Circadian cycle to minute stoichiometric interactions. And yet synthetic biologists have so far had no way of utilizing chemical ratios as means of controlling cell behavior. Until now.
With the Stanford 2010 team's ratio sensors, synthetic biologists will be able to create more responsive genetic machinery capable of solving all sorts of problems. Why not take a look at a few examples on our Applications page?
Twitter Project
Our team also created an iGEM 2010 list on Twitter to allow teams to help each other solve lab problems and share ideas. Check out our story here.
