Anti-Cotinine Antibody

Raised in rabbit against cotinine, the principal oxidative metabolite of nicotine used as a biomarker for tobacco exposure, this polyclonal primary antibody from Antibodies.com is supplied as a 1 mg purified Ig fraction. The unconjugated format allows researchers to conjugate HRP, biotin, fluorophores, or other reporter chemistries as required by each downstream application.

Because polyclonal reagents recognize multiple epitopes on the small cotinine hapten, the antibody supports competitive immunoassay development, immunohistochemistry of nicotine-exposed tissue sections, western blot confirmation, and lateral flow assay workflows. Investigators in pharmacology, toxicology, and smoking-behavior research rely on cotinine detection for quantitative studies of active use and secondhand exposure monitoring.

For routine handling, refrigerate at 4 °C for short-term use; for longer projects, store frozen aliquots at -20 °C and limit repeated freeze-thaw cycles to preserve binding activity. The product ships in a vial containing the Ig fraction suspended in a stabilizing buffer, and is intended for research use only.
