Zusammenfassung:PROBLEM TO BE SOLVED: To provide an anti-HLA (human leucocyte antigen)-DR monoclonal antibody. SOLUTION: An HLA-DR-bonding antibody having the properties: (a) it exhibits an effect of prolonging the life of a non-human animal carrying HLA-DR producing cancerous cells and (b) its suppressive activity against an immunoreaction is weaker than L243 or a functional fragment thereof is provided. Alternatively, an HLA-DR-bonding antibody that exhibits an immunosuppressive activity equivalent to a mouse anti-HLA-DR monoclonal antibody L243 (ATCC HB-55) or stronger than L243 or a functional fragment thereof is provided.
