ABSTRACT:
The invention comprises an anti-idiotypic antibody designated 2F10 and permitted variants thereof, which have antigenic properties similar to the group specific "a" determinant of human hepatitis B surface antigen HBsAg and have at least partial but not complete homology with such surface antigen. The invention further comprises a peptide having a chain comprising the amino acid residues Ala Val Tyr Tyr Cys Thr Arg Gly Tyr His Gly Ser Ser Leu Tyr and permited variants thereof, which, like 2F10, have antigenic properties similar to the group specific "a" determinant of human hepatitis B surface antigen HBsAg and have at least partial, but not complete, homology with said surface antigen. The amino acid sequence is found in and forms a part of 2F10. The shorter peptide chain comprising the amino acid residues Gly Tyr His Gly Ser Ser Leu Tyr and permited variants thereof, also have antigenic properties similar to the group specific "a" determinant of human hepatitis B surface antigen HBsAg and have at least partial, but not complete, homology with said surface antigen.
