Used to measure alkaline phosphatase (AP) enzyme activity in fish samples, this ELISA kit is widely applied in aquaculture and marine biology research. It helps assess fish health, immune response, and organ function, particularly in studies related to environmental stress, disease infection, and toxicology. The kit enables quantitative analysis of AP levels in serum, tissue homogenates, and cell cultures from various fish species. It is commonly used in immunological monitoring, early disease detection, and evaluating the impact of feed additives or pollutants on fish physiology. Due to its sensitivity and specificity, it supports research in sustainable aquaculture and aquatic biomarker development.
