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.
Screening Plasmid 1.0
Terminator Characterization via Screening Plasmid 1.0
Inverter Characterization via Screening Plasmid 1.0
Screening Plasmid 2.0
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. An early list of possible improvements:
- Brighter FPs (in particular RFP is very dim)
- Emerald & tdTomato look pretty promising
- Lower copy plasmid
- New Inducible Expression System
induction system, has a larger dynamic range than pBAD and doesn't require a specialized strain. (i.e. no knockouts of native systems needed.)
