Abstract
Summary
Seven proteins in whole saliva and parotid secretion were shown to be immunochemically similar to plasma proteins by means of ring-precipitin, micro-immunoelectrophoresis and micro-double-diffusion technics employing specific antisera. By semi-quantitative measurement, the differences in protein concentration among the subjects'oral fluids were small; the highest concentrations among the proteins were invariably observed for albumin and γ-globulin in saliva, and for γ-globulin in parotid secretion. Fibrinogen was the only one of 8 plasma proteins tested which could not be detected in either oral fluid.
