The characterization of standard parts has always been one of the main concerns in Synthetic Biology. For this very same reason, iGEM teams from all around the World were suggested to take part in the biggest measurement study ever conducted and the 2015 UNITN-Trento iGEM team answered the call. The goal of this Second International Measurement Interlab Study is to assemble three different devices, each one containing a promoter with a screening plasmid intermediate and collect as many fluorescence data as possible. iGEM teams are free to use any technique to measure their devices as long the obtained data are solid and reproducible.
