by using human calcitonin ( hct ) , human calcitonin-gene-related peptide ( hcgrp ) , and a synthetic peptide with a sequence analogous to the 34 c-terminal amino acids of human preprocalcitonin ( designated as pqn-34 ) as haptens in the generation of monoclonal antibodies , we assessed the role of amido and amino groups in paratope-epitope binding .
