Scientific Background | Aquaporins selectively conduct water molecules in and out of the cell, while preventing the passage of ions and other solutes. Known as water channels, they are integral membrane pore proteins (1, 2). Aquaporin 2 is the vasopressin-regulated water channel of the apical membrane of collecting duct cells. It is located in kidney epithelial cells and usually lies dormant in intracellular vesicle membranes. When it is needed vasopressin binds to the cell surface vasopressin receptor, activating a signaling pathway that cause AQP2 containing vesicles to fuse with the plasma membrane so the AQP2 can be used by the cell (3). Defects in AQP2 area cause of an autosomal dominant form of nephrogenic diabetes insipidus (NDI) (4). |

AP (Alkaline Phosphatase)
Properties:
- Broad enzymatic activity for phosphate esters of alcohols, amines, pyrophosphate, and phenols
- Commonly used to dephosphorylate the 5’-termini of DNA and RNA to prevent self-ligation
- Catalyzes the conversion of:
- Chromogenic substrates (e.g. pNPP, naphthol AS-TR phosphate, BCIP) into coloured products
- Fluorogenic substrates (e.g. 4-methylumbelliferyl phosphate) into fluorescent products
- Molecular weight: 140 kDa
- Applications: Western blot, immunohistochemistry, and ELISA
