Overview
Catalog #	bs-70017r
Product Name	Aquaporin 2 (Ser261) Antibody
Applications	WB, IP, IHC
Specificity	Specific for endogenous levels of the ~29 kDa AQP2 protein phosphorylated at Ser261. Also recognizes the glycosylated form of AQP2 at ~37 kDa. Immunolabeling is blocked by preadsorption with the phosphopeptide used as antigen, but not by the corresponding non-phosphopeptide.
Reactivity	Human, Mouse, Rat
Predicted Reactivity	Dog, Bovine, Chicken, Non-Human Primate
Specifications
Conjugation	Unconjugated
Host	Rabbit
Source	Synthetic phospho-peptide corresponding to amino acid residues surrounding Ser261 of rat aquarporin 2, conjugated to keyhole limpet hemocyanin (KLH).
Modification Site	Ser261
Clonality	Polyclonal
Clone #	#REF!
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 g per ml BSA and 50% glycerol.
Storage Condition	Storage at -20C is recommended, as aliquots may be taken without freeze/thawing due to presence of 50% glycerol. Stable for at least 1 year at -20C.

Background	Aquaporin 2 (AQP2) is a hormonally regulated water channel located in the renal collecting duct. Mutations in the AQP2 gene cause hereditary nephrogenic diabetes insipidus in humans (Iolascon et al.,2007). A vasopressin induced cAMP increase results in the phosphorylation of AQP2 at serine-256 and its translocation from the intracellular vesicles to the apical membrane of principal cells (van Balkom et al., 2002). Recently, serine-261 has been identified as a novel phosphorylation site on AQP2 and levels of phosphorylated S261 have been shown to decrease with vasopressin treatment suggesting its involvement in vasopressin-dependent AQP2 trafficking (Hoffert et al., 2007)
