Aquaporin 2 (AQP2, AQP-CD, WCH-CD)
Description:
Water is a critical component of all living cells. Interestingly, tissue membranes show a great degree of water permeability. Mammalian red cells, renal proximal tubules, and descending thin limb of Henle are extraordinarily permeable to water. Water crosses hydrophobic plasma membranes either by simple diffusion or through a facilitative transport mechanism mediated by special protein “aquaporin”. Over the last decade, genes for several members of aquaporin family (AQP1-9 and AQPQP) have been cloned, expressed, and their distribution studied in many tissues.
AQP2 or AQP-CD or WCH-CD (mouse, rat, human 271aa; human gene locus 12q13) is the vasopressin-regulated water channel of the apical membrane of collecting duct cells. AQP families of proteins are predicted to contain six transmembrane domains. The N and C-termini are predicted to be cytoplasmic. Defects in AQP2 are a cause of an autosomal dominant form of nephrogenic diabetes insipidus (NDI).

Applications:
Suitable for use in ELISA and Western Blot. Other applications not tested.

Recommended Dilution:
Western Blot: 1-10ug/ml using Chemiluminescence. AQP2 is approx 30kD (3).
ELISA: 0.5-1ug/ml. A3000-07D can be used to coat ELISA plates at 1ug/ml.
Optimal dilutions to be determined by the researcher.

Recommended Control Peptide:
A3000-07D: Aquaporin 2, Mouse, Control Peptide (AQP-CD, WCH-CD)

Storage and Stability:
May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for at least 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
