Abstract
Phenylethanolamine A (PEA) is a phenethanolamine member of the family of β-adrenergic agonists compounds illegally used as feed additives for growth promotion. In this study, PEA was covalently linked to carrier protein cationized bovine serum albumin (cBSA) and egg albumin (OVA). A monoclonal antibody specific for PEA was produced and characteristics of monoclonal antibody (McAb) were studied. Based on the McAb, an enzyme-linked immunosorbent assay (ELISA) for detection of PEA was developed, which showed an IC50 value of 6.25ngmL−1 and a detection limit of 0.19ngmL−1. The average recovery of PEA from spiked samples was 103.4%, which demonstrated that the matrices of meat where PEA may be found do not interfere with the assay.
