Staining summary

A majority of normal tissues displayed weak to moderate cytoplasmic staining. Membranous staining was observed in ciliated cells and proximal renal tubules. Parts of the intestine as well as subsets of trophoblasts, cells in seminiferus ducts and squamous epithelia in tonsil were strongly stained. Bone marrow, the CNS, bile ducts, lymphoid tissuec and islets of Langerhans were negative.
