EasyProbe™ DAPI Fixed Cell Stain


EasyProbes™ DAPI is a commonly used nuclear counterstain for fixed cells that emits blue fluorescence upon binding to the minor groove of dsDNA. Our EasyProbes™ DAPI Fixed Cell Stain is formulated in a ready-to-use solution that is provided in a convenient-to-use dropper bottle. Just tip and drip two drops per ml to stain your cells. DAPI is widely used for nuclear and chromosome counterstain, showing a distinct banding pattern in chromosomes.


  • No need to dilute, weigh, or pipette
  • Convenient dropper bottle—just use two drops per mL
  • Excited by UV light and emits blue fluorescence at 460 nm when bound to DNA

Suggestions for use

  • In most cases 2 drops/ml and an incubation of 15 to 30 minutes will give bright nuclear staining; however, optimization may be needed for some cell types, conditions, and applications. In such cases simply add more, or fewer drops until the optimal staining intensity is obtained.
  • EasyProbes™ DAPI Fixed Cell Stain is excited by UV light at 360 nm when bound to DNA, with an emission maximum at 460 nm. It is detected through a blue/cyan filter, such as a DAPI filter set.
Excitation/Emission: 358/460 nm
