Antigen Inhibition of the Interaction between Murine Monoclonal Anti-Idiotypic Antibodies and Human Monoclonal Anti-DNA Antibodies

Abstract

MURYOI, T., SASAKI, T., TAMATE, E., TAKAI, O., HARATA, N. and YOSHINAGA, K. Antigen Inhibition of the Interaction between Murine Monoclonal Anti-Idiotypic Antibodies and Human Monoclonal Anti-DNA Antibodies. Tohoku J. exp. Med., 1987, 152 (3), 253-258-Monoclonal anti-idiotypic (Id) antibodies to human monoclonal anti-DNA antibodies were obtained by a somatic cell hybridization. One, termed as D1E2, was directed to Id of anti-single-stranded (ss) DNA antibody (0-81) and the other, 1F5, to anti-double-stranded (ds) DNA antibody (NE-1). Each anti-Id antibody behaved like a mirror image of the corresponding antigens, when determined by competitive inhibition radioimmunoassay. Therefore, D1E2 and 1F5 are regarded as Ab2β or Ab2γ. These antibodies will make useful reagents to understand and manipulate the autoantibody production in human.
