AQP9 Antibody (G-3) is a mouse monoclonal IgG2a kappa light chain antibody that detects AQP9 protein of mouse, rat, and human origin by western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), and enzyme-linked immunosorbent assay (ELISA). anti-AQP9 antibody (G-3) is available in both non-conjugated and various conjugated forms, including agarose, horseradish peroxidase (HRP), phycoerythrin (PE), fluorescein isothiocyanate (FITC), and multiple Alexa Fluor® conjugates. AQP9, consisting of 295 amino acids, plays a crucial role in facilitating the transport of water and a range of noncharged solutes across cell membranes, which is vital for maintaining osmotic balance and cellular homeostasis. As a member of the aquaporin family, AQP9 is particularly important in tissues where rapid water movement is necessary, such as in the kidneys and brain. AQP9 is also known to be permeable to urea and glycerol, distinguishing AQP9 from other aquaporins that primarily transport water. Expression of AQP9 in various tissues underscores its significance in physiological processes, including renal water absorption and regulation of fluid balance in the body. Using AQP9 (G-3) antibody in research can provide valuable insights into the functional dynamics of aquaporins and their impact on cellular and systemic water transport mechanisms.

Rated 5 out of 5 by from great qualityI have used this AQP9 antibody (sc-74409) at 1:500 for Western Blot to detect AQP9 mouse liver tissue lysates. It showed a nice band at 33kda. Not much background, works perfectly fine. I think I could have gone lower with the concentration at 1:1000 in future testing.
