Dear 2022 iGEM teams,

We would like to invite you to participate in the Sixth International InterLaboratory Measurement Study. We’re hoping this study will get you excited for iGEM and help prepare you for the rest of your project!

Reliable and repeatable measurement is a key component of all engineering disciplines. However, the ability to repeat measurements in different labs has often been difficult. For synthetic biology measurements, one of the big challenges has been that fluorescence data usually cannot be compared because it has been reported in different units or because different groups process data in different ways. Many have tried to work around this using “relative expression” comparisons. However, being unable to directly compare measurements makes it harder to debug engineered biological constructs, harder to effectively share constructs between labs, and harder even to just interpret your experimental controls. Through the InterLab study, the Engineering Committee has been developing a robust measurement procedure for green fluorescent protein (GFP) over the last several years. This year, we will even extend from one-color calibrations (green) to multi-color calibrations (green-red-blue)!

Are you interested in participating? Make sure to fill in the survey!
