Abstract:
1. Diagnostic kit for the simultaneous measurement of antibiotics of different classes, at least β-lactames and tetracyclines, comprising: a single reactive mixture comprising at least a first labeled receptor specific for the recognition of β-lactames, a second labeled receptor and a biotinylated fragment of a nucleic acid, so that the second labeled receptor specifically and competitively recognizes a tetracycline present in a sample and said biotinylated fragment of a nucleic acid; and a recovery system in the form of a solid support comprising a single nitrocellulose membrane on which are attached at two known and distinct sections, called test zones, an antibiotic with a β-lactame core and an avidine, respectively; in such a way that the labeling intensity detected on the recovery system in both test zones independently results from the competitive recognition of each antibiotic by its labeled receptor.
