Experimental Notes:

• Deviations from protocol/procedure supplied by manufacturer.
• Step 1: Heated tissue 60°C for 30 minutes; manufacturer heats for 45 minutes.
• Step 2: No ethanol wash was performed during deparaffinization; manufacturer includes 1 wash of 80% ethanol for 3 minutes.
• Step 3.1: Slides heated for 15 minutes; manufacturer provides a range of 15-20 minutes.
• Step 3.2: Slides cooled for 30 minutes; manufacturer cools for 20 minutes.
• Step 4: Italicized reagents and incubation time are fixed instrument parameters.
• Step 5: Secondary species-specific serum block not used; manufacturer blocks with 5% normal goat serum for 2 hours.

Target Details for AQP2

Target: AQP2 (Aquaporin 2 (Collecting Duct) (AQP2))

Alternative Name: AQP2 (AQP2 Products)

Synonyms: AQP-CD antibody, WCH-CD antibody, cph antibody, jpk antibody, AQP-2 antibody, aquaporin-2 antibody, aquaporin 2 antibody, aquaporin 2 (collecting duct) antibody, Aqp2 antibody, AQP2 antibody

Background:

Synonyms: AQP-CD, WCH-CD, Aquaporin-2, AQP-2, ADH water channel, Aquaporin-CD, Collecting duct water channel protein, Water channel protein for renal collecting duct, AQP2

Background: Forms 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.

Gene ID: 359

UniProt: P41181

Pathways: Response to Water Deprivation
