Figure 5. Immunohistochemistry: Ovarian cancer tissue arrays comprised of both clear cell and serous ovarian cancers. Hematoxylin and eosin staining is shown in panels A (serous) and B (clear cell). Staining of a representative case of serous and clear cell, respectively, were stained with antibodies against EPCAM, (C, serous; D, clear cell); Annexin IV, (E, serous; F, clear cell); HE4, (G, serous; H, clear cell); and WT1, (I, serous; J, clear cell).
