Representative two-dimensional electrophoresis (2DE) of whole saliva (WS). Two-hundred µg of proteins were separated by 2DE using 18 cm pH 3–10 linear strip and 12% SDS-PAGE. Gels were stained by fluorescent dye. All circled spots indicate proteins identified by nano-LC-ESI MS/MS with gene names also reported in Table 3 and Table 4.
