Cotinine-3-HRP Antigen

Designed for use as a tracer in cotinine immunoassays, this ready-to-use antigen-HRP conjugate from Antibodies.com targets Cotinine-3 and is supplied as a 1 mL liquid formulation. The product is presented as an Antigen-HRP conjugate and is validated for ELISA applications, making it well suited to laboratories developing or running nicotine-exposure assays, tobacco-smoke monitoring kits, and related drug-of-abuse immunoassays. The conjugate is prepared in 100 mM Tris base buffer at pH 7.0, supplemented with 100 mM FBS, 0.0016 % gentamicin sulfate and 0.005 % thimerosal as preservatives to maintain enzyme activity during storage and handling. For best results, store the vial at +4 °C, where it remains stable for up to twelve months; the product must not be frozen, as freeze-thaw cycles will compromise the HRP activity and conjugate integrity. As a small-molecule (hapten) conjugate rather than a full antibody reagent, host species, clonality and isotype are not applicable, and reactivity is defined by binding to anti-cotinine capture antibodies in ELISA rather than to a defined tissue or species panel. Each lot is released for research use only and is not intended for diagnostic or therapeutic applications. The conjugate is dispatched from the Antibodies.com facility in Cambridge, UK, typically on a short lead time, allowing research teams to integrate the reagent quickly into existing cotinine detection workflows.
