From: The proteomic profile of whole and glandular saliva in healthy pain-free subjects

A typical two-dimensional electrophoresis (2-DE) gel map illustrating the salivary protein pattern and expression.
The diagrams show the integrated optical density (IOD) of the protein in the individual gel from the different saliva samples. The different saliva samples are marked with different colors as indicated in the legend. N represents the number of subjects in each group. The diagrams illustrate the variation in the expression level of typical saliva proteins in the different saliva samples. (A) Prolactin-inducible protein, (B–D) isoforms of Cystatin S, (E) Cystatin SN), (F) Alpha-amylase.
