This year, our team participated in the iGEM Fourth InterLab study. The objective of this study is to improve the measurement tools in order to obtain more reliable data within the field of synthetic biology. This year’s study aimed to improve the GFP and OD600 measurement protocol via the use of a plate reader. We were provided with 8 plasmids, including 2 controls and 6 test devices, to transform into DH5-alpha Escherichia Coli cells. We measured the fluorescence and absorbance with the Molecular Devices Microplate Reader SoftMax Pro 6.5.1.
