[Histonet] ER/PR question

[Rene J Buesa]

Time alone is not the only cause for antigen decay for it is also associated with storage conditions and, as such, you cannot "predict" % decay based on time alone.Just try one block and let the pathologist decide based on the usefulness of what he sees in that try test.René

 Good Morning,
One of my Pathologists wants me to do some ER/PR's on 9 year old tissue blocks.  I know ER and PR can be sensitive are the IHC's going to work or will there be too much antigen decay?

Thanks,
