Anti-AVPR1a antibody is validated on mouse tissue and recommended for immunofluorescence labeling, IHC, or western blot of materials from rodent and human tissues.

Vasopressin receptors are G protein coupled receptors. There are three subtypes of vasopressin receptor: AVPR1a, AVPR1b, and AVPR2. These three subtypes differ in localization, function and signal transduction mechanisms.

Vasopressin receptor subtype V1a (AVPR1a) is encoded by the AVPR1A gene in human. AVPR1a receptor is of 47 kDa and consists in seven transmembrane domains. AVPR1a receptor is expressed by the smooth muscle cell, the platelet, the myometrium and the nerve cell.
