Morphine-HRP Antigen

Formulated as a 1 ml liquid preparation that pairs the small-molecule morphine hapten with horseradish peroxidase, this antigen-HRP conjugate from Antibodies.com enables direct enzymatic signal generation in ELISA workflows without the need for a labeled secondary antibody. The morphine derivative is conjugated directly to HRP, so once the conjugate is captured or competed at a coated plate, signal develops on addition of an HRP-compatible substrate.

Typical use cases include deploying the conjugate as a tracer in competitive immunoassays built around anti-morphine antibodies, with applications in antibody pair screening, affinity ranking, and pharmacokinetic study support. Forensic toxicology research programs also use the reagent when developing or validating in-house assays for morphine-class small molecules. Because the enzyme is already conjugated, the preparation can be added directly to coated wells or pre-mixed with antibody samples before plate loading, simplifying assay setup and reducing handling steps.

For storage and handling, the vial should be kept refrigerated and protected from light to preserve enzymatic activity; aliquoting on receipt is recommended to limit freeze-thaw exposure that can degrade the HRP label over time. The preparation is supplied for research use only and is not cleared for in vitro diagnostic or clinical applications.
