AQP Antibodies

AQP (Aquaporin) antibodies are used to detect and study aquaporins, which are a family of water channel proteins responsible for regulating water transport across cell membranes. Aquaporins play critical roles in various physiological processes, including maintaining water balance, facilitating fluid transport, and contributing to cellular homeostasis.

Structure and Function of Aquaporins

Structure:
- Channels: Aquaporins form tetrameric structures, with each monomer contributing to a central water-conducting channel.
- Domains: Each monomer consists of six transmembrane alpha-helices, forming a core structure that facilitates water passage.
Functions:
- Water Transport: Facilitate the rapid and selective movement of water molecules across cell membranes.
- Fluid Balance: Regulate water balance in tissues and organs, influencing processes like urine concentration and secretion of fluids in glands.
- Cellular Homeostasis: Maintain cellular osmotic balance and support cellular functions in various tissues.

Applications of AQP Antibodies

Western Blotting:
- Purpose: Detect and quantify aquaporin proteins in cell or tissue extracts.
- Application: Study expression levels, analyze protein modifications, and evaluate responses to treatments.
Immunohistochemistry (IHC):
- Purpose: Localize aquaporins in tissue sections.
- Application: Investigate tissue-specific distribution, subcellular localization, and expression changes in various pathological conditions.
Immunoprecipitation (IP):
- Purpose: Enrich aquaporin proteins from cell lysates.
- Application: Study protein-protein interactions and post-translational modifications.
Enzyme-Linked Immunosorbent Assay (ELISA):
- Purpose: Quantify aquaporin levels in biological fluids or cell lysates.
- Application: Measure changes in aquaporin expression and activity under different experimental conditions.
