title: Electrophoretic analysis of cat parotid saliva in response to parasympathetic stimulation or infusion of bethanechol.
abstract: The protein constituents of cat parotid saliva evoked by parasympathetic stimulation or the infusion of bethanechol have been compared by sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE). The SDS-PAGE patterns were highly reproducible for an individual cat and revealed up to 30 polypeptide bands in microlitre volumes of unconcentrated saliva. Only minor and predominantly quantitative differences were detected in the salivary protein composition of different cats. SDS-PAGE demonstrates quantitative rather than qualitative changes in the protein composition of saliva evoked in response to different stimuli. The latter included preliminary observations on the effect of vasoactive intestinal peptide (VIP) on the bethanechol-evoked response.
