Title
Time-lapse FRET images of Booster-PKA in reporter COX-DKO-HeLa cells cocultured with producer HeLa cells
Description
Time-lapse FRET images of Booster-PKA in reporter COX-DKO (COX-1 and COX-2 deficient)-HeLa cells cocultured with producer HeLa cells. In the producer cells, optogenetic calcium channel stimulator: OptoSTIM1 (CRY2clust) is expressed, and PGE2 (prostaglandin E2) is generated after blue light flash. It is released and binds to the EP2 on the reporter cells and induces the FRET of PKA biosensor, Booster-PKA. These serial processes reveal the coverage of PGE2 around one activated cell.
