[Studies on the recognition of specific sensitization to tumor antigens by measuring passive electrical additive effects as against the electrophoretic mobility test].

Lymphocytes from cancer patients were incubated with different tumor antigens. In the medium in which the lymphocytes were suspended, passive electrical values could be measured in the Mc region. These values correlate with a specific sensibilization of tumor carriers. By comparison with the electrophoresis-mobility test (em-test) we found in 66 out of 74 supernatants, using CEA and KCl-extracts as antigens, a good conformity of the two reaction patterns.
