[Histonet] DAPI vs. Hoescht

[Gayle Callis]

You can try Vectashield hard set with DAPI, and not find it so pricey. It 
also has antifade properties.  One thing is to have the correct filter on 
the microscope for DAPI, and it takes a special laser for confocal.  I 
would vote for the DAPI, it is right in the mounting media and is done in 
an instant when you mount the coverslip, no optimization is needed.  It 
stains the DNA without problems, and extremely easy.

If you have autofluorescence, look into Molecular Probes Image iT signal 
enhancer.

We love the Molecular Probes Prolong Gold antifade with DAPI, hard set - 
and ignore the expense in favor of excellent results.
