title: The dimeric structure of carcinoembryonic antigen (CEA).
abstract: The results of SDS-polyacrylamide gel electrophoresis and cross-linking experiments indicated that carcinoembryonic antigen is a dimer composed of two identical or closely similar noncovalently bound subunits, dissociating on heating in the presence of SDS. The dissociation is reversible upon the detergent removal.
