PCCs are designed to bind to and detect designated motifs (epitopes) on target proteins. They are developed by using a designated region (the epitope) of the protein target as the catalytic scaffold for assembling the PCC. This epitope-directed process lends exquisite selectivity to the PCC. The small size of the resulting molecule – approximately one-fortieth the molecular weight of an equivalent monoclonal antibody – suggests a new class of diagnostic and therapeutic agents that resembles a peptide therapeutic with antibody-like binding properties.
