Used in environmental and aquatic research to detect and quantify vitellogenin (VTG) levels in fish, this ELISA kit helps assess endocrine disruption caused by environmental pollutants such as estrogenic compounds. Elevated VTG in male or juvenile fish indicates exposure to xenoestrogens, making the kit a valuable tool in ecotoxicology studies, water quality monitoring, and risk assessment of industrial, agricultural, and municipal discharges. It supports regulatory testing and environmental impact evaluations by providing a sensitive and specific measure of estrogenic activity in aquatic ecosystems.
