They require BRET-formatted biosensor components and instrumentation capable of measuring bioluminescence resonance energy transfer in live cells. The exact construct pairings are not given in the payload.; requires BRET-compatible donor and acceptor biosensor components; requires luminescence-capable live-cell measurement instrumentation
The provided evidence does not establish that BRET biosensors alone resolve all subcellular localization questions or all downstream signaling branches. They are one assay class within a broader optical toolkit.; the provided payload does not specify exact sensor architectures or performance tradeoffs
