This laboratory participated in the Second UKEMS Collaborative Study, contributing to the work of the bacterial group. Our task was to test DAB and its analogue CDA, with both uninduced rat liver S9 and chicken liver S9. The test chemicals, S9 and bacterial cultures were provided by the study organisers, and we employed standard methods and experimental design as required. The results that we obtained are described below.
