Hi, Teri:

        Thank  you  very  much  for  your  further suggestions. As to the
   slides,  we  use  SuperFrost  Plus  slides which is ready to use. So I
   don't  do  anything  to  the  slides.  Before starting in situ, I only
   air-dry  the  slides  briefly.  Actully,  I  didn't  realizae it is an
   important step before you point it out. How long do you usually do?
