ETH Zurich

ETH Hoenggerberg with the new HIT building

The ETH Zurich is an Insitute of Technology, focusing mainly on the natural sciences and engineering. Locals sometimes refer to the ETH as the "Poly", derived from its historical name "Eidgenössisches Polytechnikum" or "Federal Polytechnic Institute".

Like its sister institution, the "École Polytechnique Fédérale de Lausanne" (EPFL), ETHZ is a federal university; the remaining ten universities of Switzerland are cantonal. ETHZ was founded around the same time as MIT (1855) and for similar reasons (to develop the local industries and provide these with the necessary professionals). ETHZ has two campuses in Zurich: the old campus downtown (under constant development, of course), with a focus on engineering, applied natural sciences and mathematics; and the new campus on the Hönggerberg, with a concentration on the natural sciences and the building sciences.

ETHZ is an internationally oriented university. It is a founding member of the "IDEA League" and the "International Alliance of Research Universities" (IARU).

Our lab

Our Workingplace

For our work on the iGEM project, Prof. Panke provided us with working space in his "Bioprocess Laboratory" of the ETH Zurich.

CAB/CNB Building

It is located in the CNB building in the center of Zurich.

Multipurpose Cell Lines

Our system has the ability to behave in different ways according to an internal toggle inside it switching states based on the chemical substances that the system is exposed to. The toggle states could generally be used to trigger events such as enzyme synthesis, transcriptional regulation, virion production, or even cell death. Therefore, one may view the bacterial cell line containing this system as a multipurpose cell line. By adding a certain chemical to a cell line, the latter may be trained to exhibit a desired behavior, and then it is not necessary any more to construct two independent cell lines.

This means that one applies an “input engineering” instead of a “DNA engineering” approach. If one extends this idea to several multi-inducible toggle switches being harbored in the same cell line, the number of possible phenotypes increases to 2n, where n equals the number of toggle switches. For example, if one would have 5 such toggle switches inside a cell line, 32 different behavior patterns would be possible.

For the purpose of creating a toggle switch that is activated in a specific phase only and not always (a multi-inducible toggle switch), as is required for stable biological automatons, we introduced the concept of double promoters to the Registry of Standard Biological Parts, which can be helpful for engineering systems which exhibit a desired behavior only at specific times.

Abstract from the [http://parts.mit.edu/wiki/index.php/ETH_Zurich_2005 2005 ETHZ iGEM Wiki]:

The project of the ETH Zurich team consists of the design and in vivo implementation of a gene circuit that can count to 2. In essence, the counter uses two toggle switches, each storing 1 bit, to keep track of the 4 internal states. The design of the counter is highly modular, with the hope that it can be included as a unit in larger circuits, and also combined with further counter instances to keep track of a much larger number of states, up to 2^n with n units. To facilitate further developments and integration to other projects, the parts of the counter are available in form of BioBricks. Among many exciting applications, the availability of a counter enables the execution of sequential instructions, and therfore paves the way for the execution of artificial programs inside living cells.
