The Effect of Monomolecular Spreading on the Antigenicity of the Soluble Surface Proteins of Paramecium

Abstract

The highly antigenic soluble surface proteins (serotypic antigens) of Paramecium aurelia are becoming subjects of increasing interest for the study of the genic control of protein synthesis. Sonneborn and Le Suer (1948) demonstrated in a genetically homozygous stock the existence of several distinct serotypes only one of which was detectable at a given time.
