[Histonet] silver question

Check the mountant you are using. Some will fade Spirochete silver stains
very quickly

Subject: [Histonet] silver question


All:
 
Has anyone experienced a problem with their Steiner's "fading" after a
period of time?  We had a slide that had been stained with the Steiner
procedure and it was very positive, however when it was reviewed at a
much later date it appeared negative.  Another section was stained and
it was positive.  I know that leaving the sections for a long time in
xylene before they are coverslipped can lead to fading but wouldn't this
be apparent when the slides were originally viewed?  
 
Any suggestions?
 
Thanks!
