Anti-Diphenhydramine Antibody

Raised against diphenhydramine, a first-generation ethanolamine-class antihistamine relevant to pharmacology, forensic toxicology, and clinical research, this rabbit polyclonal antibody is supplied as a Protein A purified Ig fraction. Produced by Antibodies.com at 1 mg per vial, the unconjugated preparation provides ample material for assay development, plate coating, or downstream conjugation with enzymes, biotin, or fluorophores of the user's choice.

Because the reagent is unconjugated, end users can pair it with HRP, alkaline phosphatase, or fluorescent reporter labels to suit their detection platform, supporting flexible immunoassay work targeting the parent drug or its structurally related metabolites in buffered matrices. The vial should be kept refrigerated; for extended storage, freezing at -20 degrees C in single-use aliquots minimizes repeated freeze-thaw cycles and preserves binding activity of the Ig fraction.

Intended for research use only, this reagent supports laboratories developing antihistamine detection methods, conducting residue analysis, validating analytical methods, or performing pharmacokinetic monitoring studies on antihistamine exposure.
