ABSTRACT:
The present invention relates to novel immunologic reagents and their use in assays for the detection of polycyclic aromatic hydrocarbon (PAH)-DNA or heteropolycyclic aromatic hydrocarbon (HAH)-DNA adducts. These adducts are uniquely important biomarkers for cancer risk due to exposure to environmental PAH and HAH pollutants. More particularly, this invention relates to new hapten-protein conjugates and their use as antigens in the production of antibodies for use in immunological assays for PAH and HAH biomarkers. The invention also relates to novel, chemically-pure DNA adducts of PAH or HAH which form the haptenic moieties of the conjugates of this invention, and to improved methods for their synthesis and isolation.
