Hi Everyone!
I have seen unstained slides save a patient from re-biopsy many times.
Usually it will be a case where a patient has a known diagnosis, like lung
cancer. In these types of cases after diagnosis molecular testing (and IHC
for PD-L1) is usually ordered. There have been countless
To expand on what we do at our research lab; we use 6 months as a standard
maximum age of unstained slides. Also in the staining protocol for each
antibodyl we have a specific shelf life for the diluted Antibody and a
maximum age of unstained slides.

I agree with Jamie
Only a few Ags are "oxidised" ( that's the term used, I recall) but, don't let
it be YOUR protein of interest.
If you really are concerned, cut fresh sections and immunostain along with your
stored sections.
Imho: cut as few sections as you need.
Store any unused at 4C
I’m a histology workflow consultant that visits many AP laboratories
each year. Almost every laboratory has a different retention policy.
The average of most laboratories is to hold onto unstained slides for
three weeks after final sign out. Typically the unstained slide can be
held for a long

Hello My Fellow Histo
It depends on the stability of the protein and fixation, some are stable
for a week some for years. We use 6 months as a standard.

Hello My Fellow Histologists,
Happy Friday Eve.

Not for H but tests like IHC and molecular testing. These slides have
been cut, stored at room temperature, not sealed in anyway, and kept in a
cardboard box.
