title: Inhibition of a common human anti-hepatitis B surface antigen idiotype by a cyclic synthetic peptide.
abstract: A common human anti-hepatitis B surface antigen idiotype-anti-idiotype reaction was partially inhibited by a cyclic synthetic hepatitis B surface antigen peptide. Reduction of the intrachain disulfide bond and subsequent alkylation destroyed its inhibitory activity, suggesting that a conformation-dependent group alpha epitope was associated with this cyclic peptide.
