Seven mouse monoclonal antibodies (IgGs) were produced against rat neurophysins (NPs). Three were specifically directed against vasopressin-associated NP (NP-AVP), and four were specific for oxytocin-associated NP (NP-OT). These specificities were observed in liquid phase assays, immunoblot, and immunoprecipitation experiments. Homozygous Brattleboro rat(More)
Using three different monoclonal antibodies against rat neurophysins (5), with protein A-gold as immunocytochemical marker (27), the murid hypothalamoneurohy-pophysial system was studied at the ultrastructural level. Postembedding staining was done on epoxy-embedded sections of supraoptic nuclei and posterior pituitaries. Specific immunolabeling of(More)
Two anti-neurophysin monoclonal antibodies (MABs), PS 36 and PS 41, described in the preceding paper (Ben-Barak, Y, J.T. Russell, M.H. Whitnall, K. Ozato, and H. Gainer (1985) J. Neurosci. 5:000-000), allowed us to specifically stain for oxytocin-associated neurophysin (NP-OT) or vasopressin-associated neurophysin (NP-AVP) in the hypothalamus of developing(More)
