[Histonet] Question on epithelial staining in plastic resin

From:"Herrick, James L."

Hello everyone,

I am using a steamer for antigen retrieval with the solution Retrievit-8
from InnoGenex. I have tried anywhere from 15 minutes to 1 hour in the

Any feedback on this issue would be greatly appreciated. Thanks for your
