The methods used for the preparation of membrane proteins. A, shows the sucrose density gradient method, B, shows the Triton X-100 solubilization method and panel C exhibits the carbonate extraction procedure. The procedure used in panels A and B generally used to compare the efficiency of these methods to prepare as many membrane proteins as possible from P. syringae Lz4W. The procedure used in panel C was used for identification of more proteins and validate the protein/peptide identifications.
