A process of purifying target molecules is described that involves the selection of ligands based on identifying, in real time, association and dissociation constants with a given target molecule; using this information to select at least one ligand that exhibit predetermined association and dissociation constants with a given target molecule; anchoring a quantity of ligand to an activated solid support; contacting a quantity of target molecules with the anchored ligand(s); removing low affinity target molecules from anchored ligand and eluting particularly pure target molecules.

Immunological conjugates of HIV-specific selected principal neutralization epitopes are prepared. These epitopes bind 19b, a broadly neutralizing human monoclonal antibody specific for the HIV gp120. The epitopes are identified from oligopeptide epitope libraries. The conjugates are useful for vaccination against AIDS or ARC, as well as in the production of other HIV-specific broadly neutralizing antibodies for passive immunity against AIDS or ARC.
