title: A comparison of alveolar plate proteins in two species of Euplotes.
abstract: Major subunit proteins of the alveolar plates in Euplotes eurystomus and E. aediculatus have been identified by differential extraction and immunolocalization experiments. The results indicate the presence of three subunit proteins in each species (MW 96-125 kD). The proteins differ from each other in electrophoretic properties but are antigenically related. Monoclonal antibodies have been found which recognize the proteins of both species. Attempts to demonstrate intracytoplasmic precursors of alveolar plates using antibodies have not succeeded. The nature and development of alveolar plates are discussed.
