<i>O</i>AcGD2 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.
