Abstract Electrophoretic phenotypes of human salivary amylase (Amy1) and pancreatic amylase (Amy2) consist of complex isozyme patterns which may result from post-translational modifications of the primary products of the amylase loci. Biochemical separation of the two molecular weight families of salivary amylase and development of a new electrophoretic system have allowed the identification of complete isozyme patterns corresponding to variant alleles in Amy 1 and Amy2 heterozygotes. Further, immunological studies show no nonidentities among salivary isozymes and among pancreatic isozymes, which is to be expected if each series is derived from a single gene product. Both results support the hypothesis that the primary products of the amylase loci undergo post-translational modifications. Salivary and pancreatic amylase appear to be immunologically identical.
