Hi everybody,

I'm trying to counterstain my in situ hybridizations with methyl green and=20
want to mount them in glycerol or similar.  I'd like to ask if any of you 
have done (or if it washes away with time...since all the protocols I've 
seen are followed by dehydration prior to mounting).

Also, since I can't get here the already prepared solution and I've seen 
several ways to prepare the staining solution from powder(Aldrich) any 
suggestion about how to do it??


Thanks a lot !
