Rat AQP3 (Aquaporin 3, Gill Blood Group) ELISA Kit

The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Rat AQP3. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Rat AQP3. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Rat AQP3, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of Rat AQP3 in the samples is then determined by comparing the OD of the samples to the standard curve. Protein Function: Aquaglyceroporins form homotetrameric transmembrane channels, with each monomer independently mediating glycerol and water transport across the plasma membrane along their osmotic gradient (PubMed:7517548, PubMed:7526388). Could also be permeable to urea (PubMed:7517548, PubMed:7526388). Also participates in cell permeability to H2O2 and H2O2-mediated signaling (By similarity). In skin, transports glycerol to the epidermis and stratum corneum, where it maintains hydration, elasticity, and supports lipid biosynthesis for barrier repair. In kidney, contributes to the reabsorption of water, helping the body maintain proper fluid balance (By similarity) [The Uniprot Consortium]
