Non-linear electron spin resonance (EPR) techniques suitable for measuring- proximity relationships in membranes are reviewed. These were developed during the past decade in order to measure changes sensitively in the spin-lattice relaxation time (T1) of nitroxyl spin labels covalently attached to membrane lipids or proteins. In combination with paramagnetic quenching agents and double spin-labelling, the methods were further developed for distance measurements. Selected examples are given to illustrate different methods, and types of data obtained for both integral and peripheral membrane proteins.
