 AB    Rabbit antiidiotypic antibodies (Ab2) were produced against anti-HIV-1
       antibody 0.5 beta (Ab1), which binds to gp120 of HIV-1 and shows
       virus-neutralizing activity. The Ab2 bound specifically to the Ab1 and
       their binding to Ab2 was inhibited by a recombinant fragment of gp120
       (PB1) or a peptide (residues 301-324 of gp120), both expressing the
       Ab1-defined epitope. The Ab2 induced in rats antiantiidiotypic
       antibodies (Ab3) that were Ab1-like in their binding reactivities to
       PB1, native gp120 or peptide and shared idiotopes with the Ab1. However,
       the Ab2 did not induce virus-neutralizing Ab3, probably a reflection of
       the low avidity of the Ab3 as compared to the Ab1.
