Secobarbital-HRP Antigen

This horseradish peroxidase (HRP) conjugated barbiturate hapten from Antibodies.com serves as a ready-to-use tracer for competitive immunoassays detecting secobarbital or related barbiturate analytes. Supplied as a 1 ml liquid formulation in an enzyme-stabilizing diluent, the Secobarbital-HRP Antigen preserves HRP activity through repeated freeze-thaw cycles when small aliquots are prepared for batch use. The covalent conjugation of HRP to the secobarbital hapten enables the reagent to compete with free drug in a sample for antibody binding sites, producing a quantitative read-out via HRP substrate turnover. Researchers apply this conjugate in immunoassay workflows supporting clinical toxicology, forensic screening, and pharmacology studies that quantify barbiturate exposure or anti-drug antibody responses. Each unit provides 1 ml of liquid conjugate and should be handled according to standard enzyme-conjugate storage practices to retain enzymatic activity over multiple experimental runs.
