A study of paper electropherograms of human parotid saliva from thirty-six male adults (dental students) was made using standardized techniques developed specifically for the purpose. The patterns were found to be more complex than those obtained from serum with the same methods. Pattern individuality was found for each sample, in agreement with the authors' earlier results. Nevertheless, by analytical comparison of the results, several components common to different individuals were recognized. Qualitative differences and variations in the concentration of these components determined the characteristic pattern formation for an individual saliva. This information was obtained from the mobility, position, shape, and stain criteria of detectable zones, and it defines at least some of the non-dialyzable electrophoretic entities in parotid saliva.
