I've seem something similar to this.  In these cases, there is a
lot of background or nonspecific adherance of stain (Vector Red,
due to I don't know what, perhaps bad washing for whatever
reason, pH of wash buffers?) to the glass that comes of during
dehydration.  In my experience, it usually doesn't affect the
specific staining.

I know that Vector Red is supposed to be non-soluble and can be
dehydrated and cleared, but...

I just finished up a staining round of BrdU using Vector Red
counterstained with Hematoxylin (Gill's #3) and remember seeing
lots of
red on my positive controls (intestinal samples) without using a
microscope (this is normal for my protocol).  I then ran the
slides up
through the alcohols and xylenes.  The first two racks looked
great,
but my last rack of slides (which sat in the alcohols a little
longer
than the others while I coverslipped) seemed faded and all the
alcohols
and the first xylene were tinted strongly pink.  Anyone know what
is
going on here?
