Normal cells showed moderate to strong cytoplasmic positivity. Additional nuclear staining in several tissues. Glial cells, red pulp of spleen and smooth muscle cells were weakly stained or negative.
Weak to moderate nuclear positivity and weaker cytoplasmic staining was observed in most normal tissues. Strong nuclear immunoreactivity was observed in airway epithelium, gastric mucosa, renal tubules, placenta and neuronal cells.
