Intracellular sensor spatial multiplexing via RNA scaffolds

To circumvent the limitations of spectrally multiplexing sensors, fluorescent sensors are clustered by type and spatially separated in the cytoplasm to avoid cross-talk. Each sensor is fused to an orthogonal viral capsid protein that binds to a long, repetitive strand of its corresponding RNA sequence. All sensors fluoresce green and are indistinguishable during recording but are identified with post-hoc antibody or FISH staining for each sensor-specific puncta. This spatial multiplexing strategy will allow for easier scaling of the number of fluorescent reporters of physiological activity.
