Figure 1. Overall protein composition of whole saliva resolved by SDS-PAGE and assessed by image analysis. (A) Silver stain including all individuals of the study (numbered) as well as molecular-weight standards (S), independent reference samples (B, H), and additional samples derived from individuals not included in the study (XX). Sizes of molecular weight standards (M.W.) are indicated to the left in kilodaltons (kDa). (B) UPGMA dendrogram graphically depicting the similarities between individual protein banding patterns obtained after image analysis and subsequent comparison. Patient numbers (not including 16, 21, and 25) are indicated to the right for responders (R), non-responders (N), and controls (C).
