ABSTRACT:
Several forms of immunoregulatory substances are derived from monoclonal antibodies (MAbs) that are specific for a T cell surface antigen, such as CD3, TCR, CD4, or CD8 on T cells. The substances include: a mixture of F(ab').sub.2 fragments (or other divalent binding molecules which lack Fc) which each bind noncompetitively to different monovalent antigenic epitopes on the same antigen; a conjugate including a polymer molecule, such as dextran, ficoll, or agarose, that is coupled with the binding molecules, e.g., Fv, Fab, or F(ab').sub.2, which bind to monovalent antigenic epitopes on the same antigen on T cells; a conjugate including a liposome or microbead that is coupled with the same binding molecules specific for a T cell surface antigen.
