TEM of transfectant amoebae induced for capping with ConA. ExEh30 and LMM30 strains were induced for capping and fixed, and redistribution of ConA–receptor complexes was observed by the labeling of ConA binding sites by peroxidase. The membrane region in which capped complexes are concentrated is stained in black by oxidized diaminobenzidine. Micrograph A (4500× magnification) shows the cellular localization of ConA–receptor complexes in the LMM30 strain (arrows). The membrane appears poorly folded when compared with membrane in the uroid region of the ExEh30 transfectant used as a control (micrograph B, 8000× magnification).
