Recently, copeptin, a 39-amino acid glycopeptide that comprises the C-terminal part of the AVP precursor (CT-proAVP), was found to be a stable and sensitive surrogate marker for AVP release, analogous to C-peptide for insulin. Copeptin eller CT-proAVP är en glykopeptid på 39 aa som kommer från samma precursor som vasopressin (AVP, även kallat ADH). Syntesen av copeptin och vasopressin sker ekvimolärt i hypothalamus och lagras i hypofysen. Vasopressin är en viktig regulator i vattenbalansen, påverkar hemodynamiken och har en avgörande roll för Note: Copeptin (also known as Copeptin proAVP or Copeptin AVP) and arginine vasopressin (AVP) are derived from the same precursor peptide. Copeptin has been proposed as a more stable, potentially superior, surrogate marker of AVP in the assessment of water balance disorders. Both copeptin and AVP are responsive to osmotic stimuli and increase in About Copeptin.
Activation of the AVP system stimulates CTproAVP secretion into the circulation from the posterior pituitary gland in equimolar amounts with AVP.

Copeptin (also known as CT-proAVP) is a 39-amino acid-long peptide derived from the C-terminus of pre-pro-hormone of arginine vasopressin, neurophysin II and copeptin. Arginine vasopressin (AVP), also known as the antidiuretic hormone (ADH), is involved in multiple cardiovascular and renal pathways and abnormal level of AVP are associated with various diseases. Copeptin proAVP shows a significant correlation with vasopressin, it is stable ex vivo and performs precise measurement. In addition, it is easy to manage with results available in less than one hour. Copeptin is a reliable surrogate marker of vasopressin (AVP/ADH) Copeptin helps to rule out AMI with Troponin.

Copeptin (CT-proAVP) is a 39-aminoacid glycopeptide—the C-terminal part of Copeptin is a reasonable surrogate marker for AVP and measurement of
Aug 9, 2018 The copeptin assay was an automated immunofluorescence assay (BRAHMS KRYPTOR Copeptin proAVP, Thermo Scientific Biomarkers). May 23, 2019 B·R·A·H·M·S Copeptin proAVP KRYPTOR has been registered in Canada allowing for faster, more reliable indirect measurement of

Aug 9, 2017 Copeptin (pre-proAVP) secreted in equimolar amounts with vasopressin closely reflects vasopressin release.

The extraordinary stability of Copeptin eases lab logistics: The Thermo Scientific B·R·A·H·M·S Copeptin proAVP KRYPTOR assay reliably replaces the measurement of vasopressin and opens the possibility to achieve the full diagnostic potential of this hormone in rule-out of myocardial infarction (AMI) and water-balance disorders.
In the Copeptin proAVP assay, a sheep polyclonal antibody against C-terminal proAVP is labeled with europium cryptate and a mouse monoclonal antibody against C-terminal proAVP is labeled with XL707. Copeptin is sandwiched between the 2 antibodies, bringing them into close proximity. Copeptin - The Copeptin test is used in the diagnosis of central diabetes insipidus and in the differential diagnosis of central or nephrogenic diabetes insipidus.
