Human Copeptin ELISA Kit (Colorimetric)

Copeptin is a 39 amino acid glycosylated peptide that is a proteolytic product derived from a precursor which also contains Vasopressin and Neurophysin 2 peptides. The precursor protein is synthesized and cleaved in the hypothalamus before transport to the pituitary for storage and release. Copeptin is more stable than Vasopressin and serves as a surrogate indicator of Vasopressin release. Vasopressin plays a major role in blood pressure regulation through control of water retention in the kidney and vascular tone. Serum levels of Copeptin are associated with metabolic syndrome, insulin resistance, sepsis, and heart dysfunction following myocardial infarction.
