[Histonet] Storing frozen TMA sections


I know this is an old problem but I was wondering if Patsy Ruegg or Chris 
Van der Loos or anyone for that matter could send me their protocol for 
storing frozen TMA sections. Has anyone ever tried to store them in vacuum 
sealed (Food Saver) bags? I work for a company that provides frozen TMA 
slides for customers. We section them as needed and have discovered that the 
tissue starts showing freezer artifact after going into the block about 
10-12 times. Any help would be greatly appreciated.
