Reactivity of anti-serum F2 with FP-bearing sea turtle skin by IHC. Skin tissue sections derived from sea turtles (G46) with FP were stained with hematoxylin–eosin reagent (Panels A,B) or with mouse anti-sera F2 (Panels C,D). The white arrow and black arrowhead indicate ballooning degeneration and inclusion bodies, respectively, in the tumor tissues. The scale bar in each image indicated 100 μm.
