title: Immunoregulation by covalent antigen-antibody complexes. II. Suppression of a T-cell independent anti-hapten response.
abstract: Covalent antigen-antibody complexes containing the hapten fluorescein were found to suppress the thymus-independent response to that hapten. This suppression required the presence of an intact Fc fragment in the complex but could still be established in the complete absence of T cells.
