Abstract:
Human blood group MM and NN specific structures have the same precursors. Complete sialic acid removal produced the Thomsen-Friedenreich T antigen which was transformed into Tn antigen by -galactosidase on red cells as well as on isolated T antigen. MN antigens and their precursors are most clearly defined by isologous human antisera.
