We used to use Pen-Fix as a primary fixative for breast and it works quite
well actually as it contains formalin. It is nice as it retains the color
of the tissue for photos, makes the nodes pop out so you can see them and
the fixation allows for less times in the alcohols and xylenes on your
processor. We have also found it to help our staining as it intensifies
routine and special stains and is great for routine immuno and in situ! I
am not a rep nor do I have stock in the company. We just really think this
is great stuff!!
