Fentanyl-BSA Antigen

Antigens from Antibodies.com targeting fentanyl support assay developers building competitive-binding test systems for opioid screening research. The conjugate couples the small fentanyl hapten to Bovine Serum Albumin through covalent chemistry, presented as a lyophilized, salt-free Antigen-BSA conjugate supplied at 1 mg per vial. The dried cake reconstitutes quickly in deionized water or assay buffer for coating onto membranes, plates, or nanoparticles as part of a Lateral Flow immunoassay workflow. Storage of the lyophilized powder at –20 °C preserves binding activity for long-term use, while working aliquots kept refrigerated at approximately 4 °C remain stable for routine handling; repeated freeze-thaw cycles of the reconstituted material should be avoided. The matched Anti-Fentanyl Antibody, catalog A108104, pairs with this conjugate to assemble complete capture and detection reagents, with custom and bulk quantities available on request. Research use only — not for human diagnostic or therapeutic applications.
