 | Standard Curve for Human Copeptin PharmaGenie ELISA Kit (SBES0018) |
Copeptin is a 39-amino acid peptide, mainly produced in the paraventricular neurons of the hypothalamus and in the supraoptical nucleus. It is cleaved from a protein also consisting of vasopressin and neurophysin II. Copeptin may help vasopressin folding during transportation. Vasopressin has a direct antidiuretic action on the kidney, and it also causes vasoconstriction of the peripheral vessels. Copeptin can be used as a vasopressin surrogate in clinical test. The clinical interest in copeptin testing is closely linked to the pathophysiological pathways in which vasopressin is involved, such as polydipsia-polyuria syndrome, hyponatremia, syndrome of inappropriate antidiuretic hormone secretion (SIADH) as well as heart failure and acute coronary syndrome.
