QPI
"Quad-Part Inverter"
QPI refers to a quad-part inverter, that is, a PoPS-based inverter composed of four sub-parts: a ribosome binding site, a coding region for a repressor protein (e.g., lambda cI), a terminator, and the promoter (e.g., pLamdba) regulated by the encoded repressor protein.
The efficacy of these QPI parts can be measured using a [http://www.openwetware.org/wiki/PoPS_device_screening_plasmid Screening Plasmid device]
