Figure 2. Absence of keratoepithelin deposits in the lung
A: Congo red staining showed no amyloid deposits. B: Hematoxylin and eosin (H&E) staining of lung tissue revealed no deposit. C: A control preimmune serum treatment on lung tissue. D: Immunostaining with KE2 is uniformally positive because the lung normally expresses keratoepithelin, but it is negative for pathological deposits of this protein that are characteristic of TGFBI/BIGH3-related corneal dystrophies.
