Fig. 4 Cartoon representation of EPR distance measurements, (a) Doubly labeled monomeric proteins give rise to intra- and intermolecular spin-spin interactions. In order to determine intramolecular distances, experimental data has to be corrected for intermolecular contributions, (b) Intermolecular distance measurements using singly labeled proteins in protein oligomers or aggregates. Multiples of the distance are also expected. This may be even more complicated for different types of aggregation and can be analyzed by studying a series of samples with increasing content of non-labeled molecules (diamagnetic dilution), (c) To measure intramolecular distances within oligomers/aggregates, a mixture of doubly labeled and non-labeled proteins can be used...
