<p class="wow fadeInDown">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 Interlab Study ever conducted and the 2015 UNITN iGEM Team answered the call. The goal of this Second International Measurement Interlab Study is to assemble <b>three different devices</b>, each one containing a promoter with a screening plasmid intermediate and collect as many fluorescence data as possible. The three different promoters will differently affect the GFP production and thating plasmid intermediate and collect as iGEM teams are free to use any technique to measure their devices as long the obtained data are solid and reproducible.</p>

We measured in vivo fluorescence emission in different ways using Tecan Infinite 200 PRO plate reader, Varian Cary Eclipse spectrofluorimeter, and BD FACSCanto FACS.</p>

InterLab Measurement Study

What happens when GFP meets different promoters? Are they all the same? Here is what we found out!
