Very interesting Chris! I have found sometimes this works and 
sometimes it doesn't and you get complete loss of staining - 
frustrating when one was just trying to save time to begin with!! I 
imagine it's antigen dependent but I have not had time to check.

In my opinion Betsy, if you can avoid it (because you are just doing 
it to save time instead of setting up a workshop) then avoid it ... 
it simply isn't worth the risk IMHO.
