Creative Bioarray provides in vitro mammalian cell micronucleus test (OECD 487), a genotoxicity test to detect microneuclei in the cytoplasm of interphase cells and to identify genotoxic substances that harbor chromosome damaging potential in vitro. Aneugens and clastogens can be detected by analyzing the frequency of microneuclei in cells that have undergone cell mitosis during or after exposure to the test chemical. This assay is available under either GLP (Good Laboratory Practice) or Non-GLP conditions.
