It has been my experience that Positive-charged slides can deteriorate with
age and that they should have an expiration date.  We pick up our sections
from the regular water bath that has a tiny pinch of gelatin added and dry
them overnight or even over the weekend in a 60 degree C oven.  Of course,
poorly processed tissue will wash off no matter what you try.

Also, a repeat question- Anyone aware of where I can find antibody Ki M1p-
a macrophage marker?
