[Histonet] How many years you keep paraffin blocks and slides?

[Amy Lee]

Hello histonetters,
   
  Due to the limited space of my lab I need to discard some blocks and slides. I am thinking setting a "rule" about how long I can keep paraffin blocks and slides. I need to know how other people do it. Could you share your "rules"?
   
  Thanks in advance,
  Amy
