OAcGD2 expression on normal tissues defined by immunohistology*.

*Determined by immunoperoxydase assay using mAb 8B6 as described in Material and Methods. The number of each tissue section tested ranged from 2 to 3.†The zona reticularis showed faint cytoplasmic staining and moderate granular intracellular staining;IOccasional macrophages were positive‡the Purkinje Neurons were faintly positive;§the epithelium apical surface showed staining similar to that of the isotype control antibody;II;the germinal centers of lymphoid follicles showed moderate to strong stainning;**the gray matter in the dorsal horns showed moderate staining;††the follicular epithelium showed faint cytoplasmic staining.
