SYNOPSIS The high molecular weight proteins found in isolated pellicles of Tetrahymena have been compared in several individual strains within the genus using SDS polyacrylamide gel electrophoresis. Three variants of the B-protein of epiplasm (MW 174,000; 155,000; 145,000) and 2 of the C-protein (MW 140,000; 122,000) were found among the strains examined. No variation was observed in the major kinetodesmal fiber protein (MW 250,000). The variation found between strains in the proteins of a structure which is (as far as we know) the same in all strains indicates a disjunction between evolutionary change at the 2 levels of organization. The taxonomic implications of the observed variation in structural proteins in Tetrahymena are discussed.
