Measuring how proteins interact in their natural habitat A deep dive into FLIM-FRET and the QF Pro® workflow Modern cell biology is full of interaction maps. We can pull down complexes, run mass spectrometry, and build networks that suggest who touches whom. But those approaches often share the same blind spot: they turn tissue into a homogenate. You learn that an interaction exists somewhere in the sample, but you lose the spatial and cellular context that often makes the mechanism...
