EDDP-BgG Antigen ≥99%

Methadone metabolite screening assays depend on detection of EDDP, and this recombinant antigen-BgG conjugate from Antibodies.com provides an immunogen and assay calibrator for that purpose. The conjugate pairs the EDDP hapten with a BgG carrier protein, enabling effective presentation of the small-molecule target to the immune system or to specific antibodies in immunoassay workflows.

Supplied as a liquid preparation at a 1 mg pack size with a stated purity of ≥99%, the reagent supports ELISA and western blot applications. Researchers typically employ it for polyclonal or monoclonal antibody generation, evaluating antibody cross-reactivity profiles against methadone and related analytes, or coating microplates for competitive assay development. The recombinant construction offers batch-to-batch consistency that is harder to achieve with chemically haptenized alternatives.

As the primary hepatic metabolite of methadone, EDDP is widely used in clinical drug-of-abuse screening and forensic toxicology panels. Incorporating the EDDP-BgG conjugate into these workflows helps laboratories develop and validate immunoassays capable of distinguishing methadone use from other opioid exposures across routine testing sample matrices.
