Electrophoretic Patterns of Parotid Fluid Proteins from Caries-Resistant and Caries-Susceptible Individuals

Abstract

Parotid saliva samples from caries-resistant and caries-rampant individuals were electrophoresed on polyacrylamide gel slabs. The parotid saliva of the caries-rampant group showed a significantly higher level of anode-migrating proteins, predominantly isoamylases, and a significantly lower level of cathode-migrating proteins than that of the caries-resistant group in both paraffin-stimulated and sour lemon-stimulated salivary flows.
