Low-angle X-ray diffraction is a powerful method to analyze the structure of membrane bilayers. Specifically, the techniquecan be used to determine accurately the thickness of fully hydrated bilayers. Herein details are presented showing how thistechnique can measure the difference in thickness of bilayers in detergent-resistant membranes and detergent-soluble membranesextracted from model systems known to contain both raft and nonraft domains. The observed thickness difference may be criticalin the sorting of transmembrane proteins between raft and nonraft bilayers.
