Terbium-sensitised luminescence screening method for fluoroquinolones in beef serum.

Enrofloxacin and danofloxacin are the only fluoroquinolone antibiotics approved for use in cattle in the United States. Microbial screening methods commonly used for monitoring veterinary drug residues are not sensitive or selective for fluoroquinolones. In this work, a luminescence-based screening assay was developed to detect fluoroquinolones in beef serum.
