The immobilization antigen of Paramecium aurelia is a single polypeptide chain.

H G Hansma.   

Abstract

The immobilization antigen (i-antigen) fraction of Paramecium aurelia syngen 4 is shown to contain a protease that is activated by mercaptoethaneol. After the protease has been heat-inactivated, the molecular weight of the i-antigen (similar to 250,000 daltons) cannot be decreased by mercaptoethanol treatment. It is demonstrated that the i-antigen is a single polypeptide chain. Reasons are also given why low molecular weight subunits were previously reported by other authors.
