Ceramide 2-aminoethylphosphonate, CAEPn, is distributed in a rather wide range of protostomia. Bivalve shellfish in perticular have been found to contain a very high concentration of CAEPn. Although information is accumulating about this lipid, its physiological role remain obscure. Information on the cellular and subcellular distribution of CAEPn should be helpful in considering its function. In the present study, we raised a polyclonal antibody against CAEPn, characterized the antigenic determinant, and then examined the cellular localization of these epitopes in the cryostat sections of the adductor muscle, digestive gland, gill, mantle, and pedal of the fresh-water bivalve, Cristaria plicata. In the adductor muscle, the cell membrane and extracellular matrices were moderately stained by the indirect immunofluorescence method. The cytoplasm of the digestive cell, the marginal zone of mantle, and the marsuspium and cytoplasm of the gill sections were also stained.
