Methaqualone-BSA Antigen

Prepare polyclonal or monoclonal antibodies against the sedative-hypnotic drug methaqualone using this hapten-protein conjugate from Antibodies.com. The small molecule target is covalently coupled to bovine serum albumin (BSA), a carrier that raises immunogenicity by providing T-cell epitopes and stable lysine-based linkage sites, which makes the construct well suited as an immunogen in host species such as rabbits, mice, or goats. The resulting anti-methaqualone antibodies can be deployed in competitive immunoassay development, including lateral flow cassettes and ELISA-based plate formats used in forensic toxicology, workplace drug screening, customs testing, and clinical or research laboratories analyzing seized or biological evidence.

Provided as a 1 mg liquid conjugate, this methaqualone-BSA antigen is supplied ready to dilute into adjuvant for immunization schedules or to coat microtiter plates for hybridoma screening and titer tracking. The BSA scaffold carries multiple primary amine residues for consistent hapten attachment and helps dampen batch-to-batch variability across boost rounds. Researchers building sedative-hypnotic drug panels, probing cross-reactivity against related quinazolinone analogs, or assembling custom immunoassay calibrators will find the conjugate useful both as a coating antigen and as a competing reference standard in inhibition-style assays.

For best results, refrigerate the conjugate at 4 °C, protect it from light, and aliquot upon first use to limit repeated freeze-thaw exposure that could compromise the methaqualone-BSA linkage and erode downstream assay performance.
