FQNs (Fluoroquinolones) ELISA Kit

Fluoroquinolones are a class of synthetic broad-spectrum antibiotics whose residues in foodstuffs are tightly regulated due to concerns about antimicrobial resistance and consumer safety. This competitive immunoassay from Assay Genie is calibrated against a mixed FQNs standard, allowing screening of muscle tissue, honey, milk, milk powder, eggs, and urine within a single microplate workflow. The kit includes pre-coated wells, conjugate, calibrators, wash buffer, and substrate, producing a quantifiable signal that is inversely proportional to fluoroquinolone concentration in the extracted sample. With a detection range of approximately 0.1 to 10 ppb and a sensitivity around 0.1 ppb, it is suited to verifying compliance with maximum residue limits for enrofloxacin, ciprofloxacin, danofloxacin, sarafloxacin, and related parent compounds and metabolites. Standards and conjugate should be aliquoted and frozen at -20 degrees C for extended stability, while sealed kit components are kept refrigerated and protected from light; intended for research use only and in vitro screening of food and veterinary samples.
