Abstract
Numerous bioinformatics tools allow predicting the localization of membrane proteins in the outer or inner membrane of Escherichia coli with high precision. Nevertheless, it might be desirable to experimentally verify such predictions or to assay the correct localization of recombinant or mutated variants of membrane proteins. Here we describe two methods (preferential detergent solubilization and sucrose-gradient fractionation) that allow to fractionate Gram-negative bacterial membranes and subsequently to enrich inner or outer membrane proteins.
