Mouse anti human HLA DQ antibody, clone SPV-L3 reacts with a monomorphic determinant of human class II HLA DQ molecules and strongly blocks cytotoxicity.

Distribution studies suggest that it is directed against DQ rather than DR antigens. Mouse anti human HLA DQ antibody, clone SPV-L3 has been reported to inhibit the activity of cytotoxic T cell clones.
