Hello,
     I want to cryosection collagen (bovine type I) matrixes seeded with
human stromal fibroblasts.  I am looking at collagen production by the
fibroblast.  My two questions are 1) Is it better to fix before or after
cryosectioning?  I’m using a 1% glutaraldehyde- 10% formalin fixative.  2)
After section I want to use a Hematoxylin (Modified Harris) and Eosin Y
alcoholic stain, but I’m having trouble seeing the Eosin stain.  I have
tried shortening the destaining step, but it doesn’t seem to be working. 
Also, the staining steps, some of my samples don’t want to stay on the
slide.
