Dapi staining troubleshooting
WebDAPI Staining Solution (ab228549) is a fluorescent stain for labeling DNA in fluorescence microscopy. Since DAPI passes through an intact cell membrane, it can be used to stain live cells and fixed cells. Molecular Weight: 350.25 Notes DAPI’s absorption maximum when bound to double-stranded DNA is at 358 nm and its emission maximum is at 461 nm. WebMany researchers performing IF-ICC may wish to use a fluorescent reagent that marks the cell nucleus, such as DAPI or Hoechst. Because both of these intercalate to become fluorescent within seconds of accessing the DNA, mounting medium that contains DAPI can be used to achieve nuclear stain and mounting in a single step.

WebWe recommend that you check the intensity of the staining of your positive control sample under the microscope signal at 2 minute intervals. The moment you start to see background staining appear is the moment to stop the reaction. This is done by rinsing the slides in distilled water. You can then apply a light counterstain, if desired.
