Used to measure levels of the aromatic hydrocarbon receptor (AhR) in biological samples such as cell lysates, tissue extracts, or serum. This kit is widely applied in immunological and toxicological research to study the activation and regulation of AhR, a key protein involved in responding to environmental pollutants like dioxins and polycyclic aromatic hydrocarbons. Researchers use it to investigate AhR's role in immune modulation, inflammation, cancer development, and metabolic disorders. The assay enables quantitative analysis, supporting studies in drug development, environmental health, and molecular biology where precise detection of AhR expression is required.
