## Abstract The organ distribution of the tumor‐associated car‐cinoembryonic antigen (CEA), and that of the normal tissue component NCA (non‐specific cross‐reacting antigen) have been investigated in the fetus. Organ extracts from five fetuses between 14 and 21 weeks of age were analysed by radioim

## Abstract An immunohistological study of five cases of medullary carcinoma of the thyroid was undertaken with monospecific antisera against CEA and NCA. CEA was present in different areas of the tumors: cell cytoplasm, cell membrane at its apical pole when the tumor had a pseudoglandular organiza
## Abstract Three immunogenic parts have so far been identified in the carcinoembryonic antigen (CEA) molecule. These are: determinants cross‐reacting with the normal fecal antigen (NFA) (NFA determinant); determinants cross‐reacting with the non‐specific cross‐reacting antigen (NCA) (NCA determina
