This product is specific for arginine vasopressin, also known as antidiuretic hormone.

Arginine vasopressin, is a nine amino acid peptide secreted from the posterior pituitary in response to reductions in plasma volume and increases is plasma osmolarity. Its release triggers water reabsorption due to the insertion of aquaporins in the membranes of kidney tubules which transport solute-free water through tubular cells and back into the blood.
