ABSTRACT
The hypothalamo-neurohypophysial system, containing the hormones oxytocin (OT) and vasopressin (VP) and their associated carrier proteins, the neurophysins (NPS), has been the subject of extensive investigation for more than 40 years. This system has been reinvestigated during the last decade by application of immunocytochemical methods employing the rabbit antisera to the hormones and NPS. In this study we describe the preparation and characterization of a monoclonal antibody to VP and its application in immunohistochemistry. The antibody did not cross-react with OT or arginine vasotocin (AVT). Its antigenic determinants as characterized by absorption with various VP analogs included two aromatic amino acids Phe in position 3, and to a lesser extent Tyr in 2. Tissue fixation with formaldehyde resulted in inadequate immunostaining as compared to glutaraldehyde, most likely due to interference with the aromatic amino acid determinants by the former fixative.
