ABSTRACT
Fixation of the chrysophycean flagellate Poterioochromonas malhamensis in the presence of potassium (pyro) antimonate have been carried out. Intense antimonate deposits are characteristic of the various elements of the contractile vacuole as well as a portion of the plasma membrane adjacent to the contractile vacuole. Neither pretreatment of the cells with EGTA or EDTA nor the treatment of sections with these chelators is successful in removing the antimonate precipitates. Despite this, X-ray microanalyses of these deposits indicate the presence of calcium.
