From: Pea PSII-LHCII supercomplexes form pairs by making connections across the stromal gap
Salt removal causes unpairing of purified pea PSII-LHCII supercomplexes. (a) Isolation of PSII-LHCII supercomplexes from stacked pea thylakoid membranes by sucrose density gradients either containing ( + glut) or lacking glutaraldehyde (−glut). (b,c) Electron micrographs of uranyl acetate-stained PSII-LHCII supercomplexes contained in sucrose gradient bands α3 (b) and α3G (c) upon salt removal. Scale bar, 50 nm.
