Overview
Catalog #	bs-70308r-100ul
Product Name	Pre-Pro-Vasopressin
Applications	WB, IHC
Specificity	Specific for locally produced levels of the ~ 20 kDa uncleaved pre-pro-vasopressin protein. Immunolabeling of the uncleaved pre-pro-vasopressin protein band is completely blocked by preadsorption of the antibody with the peptide used as antigen.
Reactivity	Human, Mouse, Rat
Predicted Reactivity	Non-Human Primate
Specifications
Conjugation	Unconjugated
Host	Rabbit
Source	Synthetic peptide corresponding to key amino acid residues surrounding the cleavage sites for the human vasopressin precursor peptide, conjugated to keyhole limpet hemocyanin (KLH).
Clonality	Polyclonal
Isotype	IgG
Concentration	Lot Dependent
Purification	Antigen Affinity purification from Pooled whole antiserum
Storage Buffer	10 mM HEPES (pH 7.5), 150 mM NaCl, 100 µg per ml BSA and 50% glycerol.
Storage Condition	Storage at -20°C is recommended, as aliquots may be taken without freeze/thawing due to presence of 50% glycerol. Stable for at least 1 year at -20°C.

Gene ID	551
Swiss Prot	P01185
Synonyms	ADH antibody, Antidiuretic hormone antibody, Arginine vasopressin neurophysin II antibody, ARVP antibody, AVP antibody, AVP NPII antibody, copeptin antibody, Vasopressin neurophysin II copeptin antibody, VP antibody
Background	Vasopressin is a nine amino-acid peptide hormone that plays a key role in water and blood pressure homeostasis (Qureshi S., et al 2014). Vasopressin is the end-product of a highly processed 164 amino acid pre-pro-peptide. Processing of the vasopressin pre-pro-peptide results in three distinct peptides with a 1:1:1 ratio: vasopressin, neurophysin II, and copeptin (Arroyo J.P. et al, 2021). Vasopressin is the biologically active hormone, neurophysin II is a carrier molecule for vasopressin, and copeptin is the c-terminal glycosylated end-product. Vasopressin has been thought to be primarily made in the brain, and the sole source of vasopressin stimulating vasopressin V2 receptors in the kidney until recent studies (Arroyo JP, et al 2022). This antibody specially detects uncleaved pre-pro-vasopressin, accurately identifying locally produced vasopressin versus peripheral uptake of hypothalamic vasopressin or related peptides (Arroyo J.P. et al, 2022). This key research tool aided the Arroyo group in discovering immunoreactive vasopressin outside of the brain by recognizing localized vasopressin in human and mouse kidney, specifically in the distal nephron.
