Strong cytoplasmic and membranous positivity was observed in glandular cells in female genital tract, pneumocytes, placental trophoblasts and seminal vesicle. Urothelium, islets of Langerhans and renal glomeruli showed strong cytoplasmic staining. Squamous epithelia, pancreatic ducts, subsets of renal tubules and bronchus showed moderate cytoplasmic and occasional nuclear staining. Vessel walls and endothelial cells were distinctly stained. Remaining normal tissues were weakly stained or negative.
