Dear thecitan <@t> yahoo.com (whoever this is)

I would suggest that to fix the problem, make sure you fix the tissues.

Shrinkage is often due to alcohol "fixation" rather than formal fixation

Subject: [Histonet] Separation Artifact

Hello histonet!

I'm trying to figure out the cause of some artifact in my ffpe h&e skin
slides. Every once and a while I get a batch of slides with this strange
separation artifact mostly around melanocytes. Its like there is a space
around each cell(s). Also the collagen seems to have some odd

I tried recuting to make sure there was no microtomy issues but the
artifact remains. I check my waterbath temp / soaked the blocks. Not
soaked the blocks. I'm at a loss. This happens to entire processing
batch. The doctors say they are still pathologically readable but I
still want to find a way to fix this. Sent from my Verizon Wireless
