in an attempt to assess whether amido groups when present on the side-chain of amino acids may also modulate antibody binding , a monoclonal antibody referred to as qpo1 was produced and was found to recognize an antigenic determinant localized in the n-terminal region of the pqn-34 peptide bearing a glutamine residue as the n-terminal amino acid .
