Protein Name & Synonyms:
Vasopressin-neurophysin 2-copeptin (AVP-NPII) [Cleaved into: Arg-vasopressin (Arginine-vasopressin), Neurophysin 2 (Neurophysin-II), Copeptin]
ELISA (recommended work dilution= 1:64,000)
This antibody was produced from antiserum of rabbits immunized with a polypeptide immunogen. The IgG fraction was purified by Protein G/A affinity chromatography.
Product is supplied as a powder obtained from lyophilization of purified antibody in PBS without preservatives. Reconstitute the antibody with sterile 1 x PBS to a final concentration of 1 mg/ml.
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.
