摘要

Recent studies revealed an immunoregula- tory role of natural IgG-anti-F(ab')_2 antibodies in both healthy individuals and patients with certain diseases. The implication of anti-F(ab')_2 antibodies in the pathogenesis of diseases prompted us to study the gene segment structure of their antigen-binding domains and their binding character- istics. cDNA was prepared from the lymphocytes of a patient with a high IgG-anti-F(ab')_2 serum titer. Variable heavy and light gene segments were amplified by PCR and inserted into a phagemid surface expression vector.
