title: 7S class-restricted hapten-specific paralysis by injection of thymus-independent hapten-carrier conjugate.
abstract: The shift from IgM anti-hapten antibody production to IgG anti-hapten antibody production, subsequent to challenge with a T-dependent conjugate, is inhibited in mice by preimmunization with the T-independent DNP-LE conjugate. The results suggest that DNP on levan triggers off 19A T-independent anti-hapten precursors and paralyzes 7S T-dependent anti-hapten precursors.
