Abstract

The aim of this study was to test the applicability of sodium dodecyl sulfate (SDS) agarose gel electrophoresis, electroelution and electrophoretic filtration as methods of separation, detection, and purification of high molecular weight human salivary mucin. SDS agarose gel electrophoresis of whole saliva and mucin prepared by density gradient ultracentrifugation revealed bands with molecular weights in excess of 450 kDa and between 1.6x10(6) and 2x10(6) Da. Electroelution of material from gel and subsequent electrophoresis resulted in highly purified high molecular weight material. Electrophoretic filtration, a method of collecting the material remaining from whole saliva in the slot after penetration of low molecular weight constituents into SDS polyacrylamide gel, failed to produce pure high molecular weight material. It is concluded that SDS agarose gel electrophoresis and electroelution are suitable methods for studying high molecular weight salivary mucin glycoproteins.
