Fig. 4.

Gels following CBB and PAS staining (WMS only) of WMS and PS pellicle formations on hydrophobic particles from different subjects. Lanes: saliva pre (1), saliva post (2), water wash 1 (3), water wash 2 (4), SDS 1 (5), SDS 2 (6) and boiled DTT, LDS and water (7). Boxes highlight clear differences in binding ± TGM. The box highlighted by the arrow indicates an effect only seen in 50% of the samples. It shows what appear to be a possible cross-linked proteins, perhaps statherin and histatin bound higher due to crosslinking.
