Distribution of immunoreactive alkaline phosphatase in the adult rat ileum by immunoperoxidase staining at the light microscopic level.

Our prior immunocytochemical studies using monospecific antibody to alkaline phosphatase, Bouin's fixation, and paraffin sections demonstrated a decreasing gradient of villus brush border staining from the proximal to the distal rat small intestine. In addition, we noted an unusual pattern of staining in the terminal centimeter of the adult rat ileum: the… (More)
