Cotinine-4-BSA Antigen

A liquid BSA-conjugated antigen targeting cotinine, the principal oxidative metabolite of nicotine. Provided as a 1 mg conjugate in vial format, this reagent functions as both an immunogen for generating anti-cotinine antibodies and a coating or standard antigen in competitive immunoassay workflows. The cotinine moiety is conjugated through its 4-position to bovine serum albumin (BSA), which serves as the carrier protein required to elicit an immune response against the small cotinine hapten. Researchers in toxicology, addiction studies, and environmental exposure monitoring apply this antigen in ELISA platforms to develop quantitative assays for cotinine in samples such as saliva and urine. The conjugate supports antibody production protocols, immunoassay standardization, and serves as a positive reference in nicotine-exposure screening assays. Each preparation is shipped by Antibodies.com with verified quality for research use only, supporting reproducible performance across ELISA-based test development and validation studies.
