a 'two-site ' assay based on the use of 125i-labelled sheep anti- [ corticotropin- ( 2-16 ) -peptide ] igg and rabbit anti- [ corticotropin- ( 34-39 ) -peptide ] antiserum was optimized , since steric inhibition of antibody binding was avoided with this combination and because the measurement of only intact human corticotropin- ( 1-39 ) -peptide and not fragments was assured by the use of terminal antibodies .
