Paper Electrophoretic Study of a Rat Submaxillary Gland Extract †

A number of physico-chemical studies on the secretory products of salivary glands have been reported, but only a few scattered data appear available concerning constituents of the total salivary gland. In regard to electrophoresis, very few studies exist pertaining to any salivary gland protein components. Phase boundary electrophoresis studies on mucin extracts from animal salivary glands have been reported by Blix,1 McCrea,'0 and Caspary.' In this study a paper electrophoretic technique was used to study some soluble protein components of extracts from whole submaxillary glands of rats.
