Daniel,
I have found that saving slides with FFPE skin sections 5-10 micrometer
thick, the antigenicity declines with age, even when stored in the fridge.
I have tested slides from the same block freshly cut versus 2-3 years
stored on a microscope slide in the fridge. Whether this applies to needle
biopsies of tumor tissue I don't know...now I just section what I need and
return the block to the fridge.

I thought I'd poll the histonet community on an issue we're facing:
On needle biopsies for tumor, what, if any, is your protocol
for making unstained slides "on the front end" for potential use with
immunostains later (so that the specimen isn't exhausted producing levels
x
3, and you have good sections of tumor for immunostains)?
Is this protocol followed on all needle biopsies for tumor?
And what happens to any unused, unstained slides? Are they discarded (if
so, after how long?) or kept indefinitely?
Thanks for your input!
