In Vivo Liver Micronucleus Analysis


(MicroFlow® Kits)

Measuring DNA Damage
in Liver Hepatocytes

Exposure to a test substance can result in damage to the chromosomes or spindle apparatus of cells. During routine cell division, this type of damage can create a smaller ‘micro’-nucleus, apart from the main nucleus.

Liver hepatocytes in young animals proliferate at a high rate. Micronucleus formation in hepatocytes is a well-established marker of chromosomal damage. This makes assessment of micronuclei in liver a valuable endpoint.

In Vivo Liver MicroFlow kits use flow cytometry to quickly and reproducibly measure micronuclei.
