Method Deepetching, a technique which exposes the true surfaces of biological membranes by sublimination of frozen dilute buffer
Comments The first definitive study of this kind demonstrated that the ATP synthase complex was limited to non-stacked stroma thylakoids and that the density of those complexes was about 700 per µm2 of stroma membrane (primary source).
