[Histonet] Old blocks for IHC controls

[Curt Tague]

Forgive me if this has already been discussed ad nauseum... what are your thoughts on using old blocks for IHC control, like normal breast for CK7 or AE1/AE3... if we test the tissue and it works is that sufficient or is there some added steps and requirements I should be aware of?

We have blocks up to 15 years old, looks like there is a lot of good tissue we can use if age isn't an issue.


Best and thanks!
