Published Workflows
Objective: Develop and demonstrate a genetically encoded biosensor platform for functional imaging of cell signaling without requiring modification of the target proteins.
Why it works: The platform couples a biosensor design based on directional optical properties of fluorescent proteins with linear dichroism microscopy, enabling optical readout of signaling activity without modifying the target proteins.

The source describes it as an original tri-scanning linear dichroism confocal microscope used together with FLIPs. No further hardware details are given in the abstract.; used in combination with FLIPs
Independent follow-up evidence is still limited. Validation breadth across biological contexts is still narrow. Independent reuse still looks limited, so the evidence base may be fragile. No canonical validation observations are stored yet, so context-specific performance remains under-specified.

FLIPs offer simple design, high sensitivity, multiplexing capability, and ratiometric readout without requiring target modification.
The biosensors (termed FLIPs) offer an extremely simple design, high sensitivity, multiplexing capability, ratiometric readout, and other advantages, without requiring modifications to their targets.
FLIPs were demonstrated for real-time imaging of GPCR, G protein, arrestin, and other membrane-associated protein activity.
We demonstrate the sensor performance by real-time imaging activity of G protein-coupled receptors (GPCRs), G proteins, arrestins, and other membrane-associated proteins
Using FLIPs, the authors identified a previously undescribed pronounced endocytosis-associated conformational change in a GPCR-β-arrestin complex.

FLIPs combined with a tri-scanning linear dichroism confocal microscope allow imaging of activity of nonmodified, endogenously expressed G proteins.
In combination with an original tri-scanning linear dichroism confocal microscope, FLIPs allow unparalleled imaging of activity of nonmodified, endogenously expressed G proteins.
FLIPs are genetically encoded biosensors that use directionality of fluorescent protein optical properties as their detection principle.
Here, we present a biosensor design that uses a hitherto overlooked detection principle: directionality of optical properties of fluorescent proteins.
FLIPs establish a molecular platform for imaging cell signaling.
Thus, FLIPs establish a powerful molecular platform for imaging cell signaling, allowing numerous future developments and insights.
