A competitive enzyme immunoassay for screening and quantitative analysis of azaperone-azaperol in various matrices.

Azaperone can be used as tranquilizer to prevent stress during transportation of pigs. The major metabolite of azaperone is azaperol. For control purposes the marker residue is therefore the sum of both compounds.

The EuroProxima Azaperone-Azaperol ELISA is a competitive enzyme immunoassay that is validated for the screening of tissue, urine, liver and kidney.
