InterLab is an important part in IGEM competition, whose topic is the reproducibility of protein expression(mainly GFP) from engineered biological constructs in E.coli.[1] It published an interesting but universal question,
We participated in InterLab project this year. We completely finished the work of measuring the expressional level of GFP under different promotor through the method of flow cytometry. With following the standard protocal strictly, the data is reliable.
