The screening plasmid is designed to enable fast characterization of PoPS-based parts and devices. It consists of 4 components: (1) Tunable input (2) Input measurement (3) Part/Device insertion site (4) Output measurement.
We are in the process of designing a new version of the screening plasmid to account for some of the shortcomings of the previous version. Details can be found here:
