title: Electron-microscopic studies of the CA antigen, epitectin.
abstract: Epitectin, the mucin-like glycoprotein defined by the monoclonal antibodies CA1, CA2 and CA3, has been examined by electron microscopy to determine its shape and size. It appears to be a single extended strand with a mean length of about 270 nm. The antibodies CA1 and CA2 appear to bind preferentially to a terminal site on the epitectin molecule.
