abstract：:To date only a few neutralizing antibodies against HIV-1 exist. Since these neutralizing antibodies are only rarely found in sera of HIV-1 infected individuals an active vaccine is required. We recently developed murine anti-idiotypic antibody Ab2/3H6 against monoclonal antibody (mAb) 2F5, which is one of the most pro...
