[Histonet] Fluorescence staining

[Gayle Callis]

Molecular Probes has mounting media designed to set up hard but mainly 
prevent photobleaching of fluorophore, in your case FITC?

Go to their website and look for Prolong Gold, ready to use.  We love 
it.  You mount the sections from PBS, and do not dehydrate.  They recommend 
sealing the edges of coverslip, which is done nicely with toluene or xylene 
diluted mounting media at consistency of very thin nail polish. We avoid 
latter due to alcohol in nail polish.

It is pricey but worth every penny of cost.
