Abstract: Hybridoma cell lines have been produced which secrete monoclonal antibodies that bind hygromycin B and are effective to detect hygromycin B levels as low as about 0.7 ppm. These monoclonal antibodies may be used for the detection and quantitative determination of trace amounts of hygromycin B in samples, especially in animal tissue and feed material.
