OECD 489: Alkaline comet assay (in vivo mammalian)

录制类型:测定

Validation:GLP

Models:老鼠

在体内碱性彗星(单细胞凝胶电泳)测定中用于鉴定通过检测从动物的多个组织中分离的细胞或细胞核中的DNA链或核,通常暴露于潜在的遗传毒性材料的DNA链或核。

The nuclear DNA undergoes electrophoresis under alkaline conditions (>pH 13) and results in structures resembling comets which can be observed by fluorescent microscopy. The amount of DNA breakage is based on migration of the DNA fragments.

The assay can detect single and double stranded breaks which may be repaired, resulting in no persistent effect, may be lethal to the cell, or may be fixed into a mutation resulting in a permanent viable change. They may also lead to chromosomal damage which is also associated with many human diseases including cancer.
