PHE A (Phenylethanolamine A) ELISA Kit

Phenylethanolamine A (PHE A) is a synthetic β-adrenergic agonist that has been banned worldwide as a livestock growth promoter, and residue surveillance in animal-derived foods is the primary regulatory application for this test. The Assay Genie competitive ELISA is structured for small-molecule hapten detection, relying on a microplate-based competitive immunoassay with a detection limit of approximately 0.05 ppb, rather than a sandwich antibody pair. Each kit provides reagents for 96 assays, supporting routine batch processing of feed, muscle, and urine specimens collected during farm, abattoir, or import-inspection monitoring programs.

Typical use cases include compliance screening in food-safety laboratories, veterinary drug-residue panels, and academic research into β-agonist contamination of meat products, including species-specific detection relevant to cattle and swine residue panels. Because the analyte is a low-molecular-weight compound, the competitive format allows direct antigen-antibody competition without requiring paired capture and detection antibodies. Reagents are supplied for refrigerated storage and the kit is intended for research use only, aligning with method development for surveillance of prohibited veterinary substances in food-producing animals.
