Moderate to strong cytoplasmic staining was generally observed in normal cells. Keratinized squamous epithelia and the spleen were weakly stained.
Strong cytoplasmic positivity was observed in the prostate gland and subsets of spermatocytes. Moderate positivity was for example observed in renal tubules, thyroid gland and subsets of lymphoid cells. Remaining normal cells were in general weakly stained or negative.
