<< Hi  Histonets,
 I am looking for a procedure to pre fix fatty breast tissue before
 processing, it has been suggested that acetone does a good job, but prolonged
 pre fixing could hurt the tissue.Is there a another method which will not be
 so hard on the tissue and will be able to process and cut well. >>

We manufacture a product called DISSECT AID which is a special fixative for 
fatty tissue.  Dissect Aid will fix like formaldehyde, dehydrate out the 
ancillary fat, and turn the lymph nodes a pale color in the surrounding 
tissue mass.  You can get information about this product from our website at 
http://www.decal-bone.com or you may call 1-800-428-5856 for a free sample.
