The lens of the medusa Cladonema radiatum contains protein components. Three different protein fractions were found in SDS-polyacrylamide gels. Each sample used for electrophoresis contained extracts of 60 ocelli of Cladonema. Direct comparisons show correspondence between the electrophoretic mobilities of the three fractions and bands of amphibian and bovine lens proteins and antigen-antibody reaction of bovine lens antibodies to Cladonema lens crystallins.
