AW: [Histonet] Control slide storage

[Edwards, R.E.]

Is  it    quite  as  simple  as  that, I  imagine that many  epitopes might lose "stainability" if fixation is inadequate or processing poorly controlled.

CD31 for sure.  I do recall most surface markers I used tended to be 
unstable.

AW: [Histonet] Control slide storage






Hi Patsy,
I am interested in the names of this certain epitopes, that loose
stainability after long time storage.

And I'd like to ask all the other listmembers about their experiences with
this issue. Perhaps we can make a list of "dangerous" epitopes.

Betreff: RE: [Histonet] Control slide storage

I store all cut paraffin sections for IHC control at 4dc and without 
heating
to melt the paraffin, even with that I have seen some loss of antigenicity
over long periods of time for certain antibodies.

The issue was brought up in the lab regarding the storing of IHC control 
slides. What experience has anyone had on the effects of long term storage 

and staining quality. We store the slides non preheated (with the paraffin 

still on them).
