A new system for screening antibiotics in animal feeds involves washing antibiotic-containing animal feeds with a series of organic solvents to eliminate interferences and partially separate the antibiotics. Antibiotics are then determined by using paper electrophoresis and thin-layer bioautography. This approach enables the separation and qualitative identification of 17 antibiotics currently used in animal feeds and provides the ability to detect low-level cross-contamination.
一种用于筛选动物饲料中抗生素的新系统，包括用一系列有机溶剂洗涤含抗生素的动物饲料，以消除干扰并部分分离抗生素。然后通过纸电泳和薄层生物自显影法测定抗生素。这种方法能够分离和定性鉴定目前在动物饲料中使用的17种抗生素，并具备检测低水平交叉污染的能力。
