Copeptin is a 39-amino acid-long glycosylated peptide derived from a pre-pro-hormone consisting of vasopressin, neurophysin II and copeptin. Copeptin can be immunologically tested with ease and therefore be used as a vasopressin surrogate.

The antibody is stable for at least 1 year from the date of receipt when stored at -20^°C to -70^°C. Reconstituted antibody can also be aliquotted and stored at 4^°C for 1 month or at -20^°C to -70^°C in a manual defrost freezer for many months without detectable loss activity. Please avoid freeze-thaw cycles.
