DPABH-29078 is specific for ~29k Aquaporin 2 protein phosphorylated at Ser261. It also recognizes the glycosylated form of Aquaporin 2 at ~ 37k. Binding of this antibody to the Aquaporin 2 band is blocked by preadsorption with the phospho-peptide used asForms a water-specific channel that provides the plasma membranes of renal collecting duct with high permeability to water, thereby permitting water to move in the direction of an osmotic gradient.Shipped at 4°C. Upon delivery aliquot and store at -20°C. Avoid freeze / thaw cycles. *   http://www.creative-diagnostics.com/Anti-AQP2-PAb-207211-489.htm
