Most membrane glycoproteins are integral components of the lipid bilayer, and therefore contain a hydrophobic sequence. Several methods are available for characterization of these hydrophobic components: These include hydrophobic labelling, sequence determination, hydrophobic chromatography and phase partition. An elegant version of the latter technique was described by Bordier (1981). This consists of using a non-ionic detergent with a cloud-point somewhat higher than room temperature to partition proteins into hydrophobic and hydrophilic fractions.
