Used for the quantitative determination of Rat Aquaporin 8 (AQP8) in biological samples such as serum, plasma, and tissue homogenates. This ELISA research kit enables researchers to measure AQP8 levels accurately, supporting studies related to water transport, cellular homeostasis, and oxidative stress in rat models. It is commonly applied in research on liver function, kidney physiology, and gastrointestinal diseases where aquaporin expression is altered. The assay is useful in preclinical studies to evaluate disease mechanisms and therapeutic responses involving AQP8 regulation.
