[Histonet] stored unstained sections

[Terri Braud]

Cut slides stored at room temp seem to last quite a long time for routine stains, however, cut slides do demonstrate a loss of antigenicity for IHC staining, depending on the antibody.

Hi everyone,
I work in a research lab and have a number of slides that have been cut by the previous person in this position. Several slides are over one year.  I would like to know what is the standard practice for keeping cut slides? I have used them and they stain just fine but the question was brought up in a lab meeting.
How long can you keep unbaked slides? Room temperature/4C
