Help!!!  We cannot get our retic stain (Gomori's) to work.  We are
getting inconsistent results - sometimes the fibers are very, very light
and sometimes they are not there at all.  We notice a problem when we go
into the formalin after the silver.  Usually the tissue will change to
the dark gray color immediately when it hits the formalin, but it either
turns a brownish color or it doesn't change at all.  We have changed
everything in our staining set up.  Any ideas???
