fractionation of the antibodies contained in each antiserum by means of an immunoadsorbent , to which the nuclear or the mitochondrial enzyme has been covalently linked , shows that nuclear glutamate dehydrogenase ( gdh ) contains specific antigenic determinants as well as determinants common to the mitochondrial enzyme , whereas the latter appears to have no antigenic portions which are not present in the nuclear antigen , in accord with the results of immunodiffusion .
