An aminopeptidase N has been detected by immunofluorescence in the apical plasma membrane of porcine thyroid cells, facing the follicular lumen. Freshly isolated cells obtained by tissue trypsinization, lose their polarity and exhibit a homogeneous enzyme distribution over the whole plasma membrane. In thyrotropin-stimulated cultured cells organized into(More)
The cellular localization of an aminopeptidase N homologous to the brush-border intestinal enzyme and that of human blood group A-substances were investigated using the immunofluorescence technique on thin frozen sections (200 nm) of the digestive tract and associated glands of A+ and A− rabbits. Aminopeptidase N was found to be a common specific marker of(More)
