Vasopressin (AVP) — frequently asked
What is vasopressin?
Vasopressin is a nine-residue cyclic neuropeptide produced in hypothalamic magnocellular neurons and released from the posterior pituitary. It acts at V1a, V1b and V2 receptors, and is studied for its reported roles in water balance, vascular tone and neuroendocrine regulation.
Why are so many vasopressin analogs offered?
Substituted, cyclic and D-amino acid analogs were developed to separate the three receptor subtypes and to improve stability against peptidases. Researchers use them as selective agonists, antagonists or metabolically resistant probes when interpreting receptor-specific effects in tissue and cell models.
Which species sequences are relevant?
Human, rat, mouse, ovine and canine tissues all use [Arg8]-vasopressin, so one peptide often serves several models. Porcine and related species express the [Lys8] form, which matters when selecting antibodies or immunoassays for cross-species work.
