Distribution of fast- and slow-migrating Hodgkin's tumor-associated antigens.

Based on their migration in immunoelectrophoresis they have been called 5 or slow-migrating and F or fast-migrat ing antigens. These antigens are oncofetal (1) and share common antigenicity with thymic tissue. The present analy sis supports the view that F antigen was related to lympho cyte proliferation and was found in other immune processes and in a cultured Burkitt's lymphoma. S antigen increased in concentration in Hodgkin's disease, was less ubiquitous,
