Used in biological research to measure levels of the aromatic hydrocarbon receptor (AhR) in rat samples. This ELISA kit enables scientists to quantify AhR protein expression in tissues or cell lysates, helping to study the receptor's role in toxin metabolism, immune responses, and cellular signaling pathways. It is particularly useful in toxicology studies where exposure to environmental pollutants such as dioxins or polycyclic aromatic hydrocarbons is investigated. The assay provides a sensitive and specific method to monitor changes in AhR levels under experimental conditions, supporting research in pharmacology, environmental health, and disease mechanisms.
