Highly Sensitive Immunochromatographic Assay for Qualitative and Quantitative Control of Beta-Agonist Ractopamine in Foods

详细

An immunochromatographic method has been developed for the determination of ractopamine, a low-molecular, nonsteroidal growth regulator controlled in food due to toxicity. The developed analysis was characterized by an instrument detection limit of 0.05 ng/mL, a working range of 0.07‒0.28 ng/mL, and a visual detection limit of 0.5 ng/mL, which meets the requirements of sanitary and hygienic control. It is shown that the developed immunochromatographic test systems can be used to test meat products.
