Argipressin (Arg8-vasopressin) binds to the V1, V2, V3-vascular arginine vasopressin receptor, with a Kd value of 1.31 nM in A7r5 rat aortic smooth muscle cells for V1.

IC50 & Target

V2 Receptor 


In Vitro

Argipressin binds to the vascular arginine vasopressin receptor, V1, with a Kd value of 1.31 nM in A7r5 rat aortic smooth muscle cells. It also stimulates the intracellular release of calcium in A7r5 cells (EC50=5 nM)[1]. AVP-induced [Ca2+]i signals and immunized activity against S-100 in DRG cell culture. The minimum effective concentrations of Argipressin causing [Ca2+]i responses are 100 pM in non-neuronal cells in DRG culture[2].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
