Anti-Cotinine-3 Antibody

This polyclonal primary antibody from Antibodies.com targets cotinine, the principal oxidative metabolite of nicotine and a preferred biomarker of recent tobacco exposure, secondhand smoke intake, and adherence to nicotine replacement therapy. Raised in rabbit and purified by Protein A chromatography, the unconjugated Ig fraction is supplied at 1 mg per vial, giving researchers flexibility to attach custom reporters or to use the reagent directly in ELISA protocols. Cotinine's longer plasma half-life relative to nicotine makes it the analyte of choice for population-level smoking studies, and the polyclonal recognition profile broadens epitope coverage against the small cotinine hapten, an important consideration when the analyte is presented as a hapten-carrier conjugate. The reagent is intended for research use only, supporting immunoassay development in pharmacology, toxicology, occupational exposure monitoring, and behavioral addiction research where quantitative measurement of nicotine uptake is required.
