Description

Description générale

The neurophysin 1 and 2 (NPI and NPII) are carriers of peptide hormons oxytocin (OT) and vasopressin (AVP), respectively. Each NP and its associated hormon peptide are synthesized as one precursor protein, OT-NPI (UniProt P01179) encoded by the Oxt (or Ot) gene or AVP-NPII (UniProt P01186) encoded by the Avp gene in rat species. Posttranslational cleavages remove the signal peptide and process the precursor into mature OT and NPI (aa 20-28 and aa 32-135, respectively, of OT-NPI), or AVP and NPII (aa 24-32 and aa 36-128, respectively, of AVP-NPII). OT is a potent hormone and neurotransmitter secreted within the pituitary gland. OT exerts its biological activity through its receptor OXTR (also known as OTR). OT is used clinically for labor induction and may exhibit therapeutic potential for treating social anxiety disorders. AVP functions primarily as an antidiuretic and regulates the concentration of water, glucose, and salts in blood. AVP is secreted from the posterior pituitary, but exerts its biological activity in the kidney via the G protein-coupled receptor AVPR2 (V2R).

Spécificité

Clone PS 45 reacts with Vasopressin-neurophysin 2-copeptin precursor, neurophysin 2, but not Arg-vasopressin, copeptin, oxytocin, or neurophysin 1.

Immunogène

Epitope: Near Neurophysin 2 C-terminus

Application

Immunohistochemistry Analysis: A 1:250-1,000 dilution from a representative lot detected Neurophysin 2/NP-AVP in rat brain and rat pituitary tissue.
Radioimmunoassay (RIA): Target specificity of a representative lot was confirmed by RIA. Only rat neurophysin 2, but not neurophysin 1, oxytocin, or angiotensin II, can compete against 125I-neurophysin 2 for binding mAb PS 45 (Ben-Barak, Y., et al. (1985). J Neurosci. 5(1):81-97).
Electron Microscopy (EM): A representative lot immunostained granulated neurosecretory vesicles (NSVs) in all axons, Herring bodies, and terminals by EM using rat posterior pituitary LR White sections (Ben-Barak, Y., et al. (1985). J Neurosci. 5(1):81-97).
Immunoprecipitation Analysis: A representative lot immunoprecipitated radiolabelled neurophysin 2, but not neurophysin 1 (Ben-Barak, Y., et al. (1985). J Neurosci. 5(1):81-97).
ELISA Analysis: A representative lot detected neurophysin 2 immunoreactivity in rat neurophysin preparations by non-sandwich ELISA using either 125I-labelled or HRP-conjugated secondary antibody (Ben-Barak, Y., et al. (1985). J Neurosci. 5(1):81-97).
