Cannabinoid (THC)-HRP Antigen

This ready-to-use THC-HRP conjugate from Antibodies.com is a 1 mL liquid preparation built around a synthetic cannabinoid hapten covalently coupled to horseradish peroxidase. It supports competitive immunoassay development targeting the cannabinoid analyte group: because the conjugate is supplied already labelled, coated microplates or antibody and sample mixtures can be spiked directly without a secondary detection reagent. The working solution is formulated in Tris-HCl buffer at pH 7.0 with enzyme stabilizers and preserved with 0.005% thimerosal, giving a stable drop-in reagent for routine plate-based screening workflows. Its HRP reporter produces a chromogenic signal on standard TMB and other HRP-compatible substrates, supporting absorbance-based readouts commonly used in drugs-of-abuse research panels. Researchers building or optimizing cannabinoid assays can use the conjugate to probe antibody affinity, map coating-antigen orientation, or benchmark competitor lots against an in-house reference. For handling, short-term storage at refrigerator temperatures preserves working activity, while long-term storage at –20 °C is recommended and repeated freeze-thaw cycles should be avoided to protect enzymatic turnover. The product is intended for research use only and is not validated for diagnostic, therapeutic, or forensic applications. Each vial is shipped refrigerated through the Antibodies.com logistics network, and technical support is available for assay optimization and conjugation troubleshooting.
