Two types of human IgA myeloma proteins were distinguished by immunochemical tests. Seven of 51 IgA-myeloma proteins contained an an tigenic determinant that was not de tected in the other 44 proteins. The distinctive antigenic site was not dem onstrated on either the heavy or light polypeptide chains.
