in agreement with this , the staining of the nerve cells can be abolished by absorbing each antiserum with either oxytocin , vasopressin , [ lys8 ] vasopressin , vasotocin , mesotocin or isotocin , indicating that the antigenic determinant of hydra cross-reacts with those antibody subpopulations , which recognize common portions ( sequence 1-2 , 5-7 , 9 ) of the oxytocin/vasopressin-like peptides .
