Cannabinoid (THC)-BSA Antigen

The Cannabinoid BSA conjugate from Antibodies.com is a hapten-carrier immunogen supplied as a 1 mg liquid preparation of the tetrahydrocannabinol (THC) hapten covalently coupled to bovine serum albumin. Because the cannabinoid molecule is too small to provoke an immune response on its own, conjugation to this high-molecular-weight carrier enables reliable antibody generation and reproducible assay development in the laboratory.

Common research workflows include animal immunization for the production of polyclonal or monoclonal anti-THC antibodies, use as a coating antigen in competitive immunoassays, incorporation into lateral flow test development, and routine application as a calibrator or positive control in cannabinoid screening protocols. The BSA scaffold presents multiple accessible lysine residues for stable hapten coupling, supporting consistent conjugate behaviour across production batches and minimizing lot-to-lot variability in immunisation studies.

For handling, the liquid conjugate should be aliquoted upon receipt and stored frozen at -20 degrees C; repeated freeze-thaw cycles should be avoided because they progressively compromise antigenicity and reduce the working titre of downstream antibody preparations. All work should be performed under standard research-use-only laboratory conditions with appropriate personal protective equipment, given the psychoactive character of the target hapten and the protein-based nature of the carrier.
