Human Micronucleus

Measuring DNA Damage
in Red Blood Cells

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.

When red blood cells mature themain nucleus is expelled. Micronuclei remain behind, and can easily be seen in a cell with no other DNA. This makes red blood cells ideal for measuring this endpoint.

In human blood, these ‘micronuclei’ are sometimes referred to as Howell-Jolly Bodies (HJB).


  • Requires Minimal Amounts of Blood
    Collect approximately 120 µl of blood per sample.
  • Takes Advantage of Magnetic Columns
    Enrich samples by separating young and old red blood cells.
  • Includes Calibration Standards
    Malaria Biostandards ensure proper flow cytometric setup.
  • Analysis by Flow Cytometry
    Automated scoring provides objective and reproducible results.


  • Easily Integrate with Existing Studies
    Use with epidemiological studies or clinical trials.
  • Measure Very Rare Events
    This is the first time this endpoint has been available for routine use!
  • Provides Reproducible Data
    Calibration standards ensure confidence in your results.
  • Fast Turn Around, Reliable Results
    Get your data as soon as possible using laser-based technology.
