The localizations of calcium-adenosine triphosphatase (Ca2+ -ATPase) and carbonic anhydrase II (CAII) in the shell gland of the hen oviduct were examined by immunohistochemical technique.<br>Immunoreactions showing Ca2+ -ATPase localization were observed strongly in the luminal surface of the tubular gland cells and in the excretory duct of the tubular gland, but not in the epithelial cells. On the other hand, Immunoreactions showing CAII localization were observed strongly in the cytoplasm of epithelial cells and moderately in the cytoplasm of tubular gland cells. In the shell gland, these immunoreactions showing Ca2+ -ATPase and CAII localization were not different at between 3 hours and 12 hours after oviposition.<br>These results suggest that Ca2+ is secreted by active transport of Ca2+ -ATPase into the shell gland lumen from the tubular gland and HCO3- is produced and secreted in the surface epithelium rather than in the tubular gland.
