IHC for Glutaraldehyde fixed tissue?
Hello. I have some old cat brain tissue that was fixed in 2% Glutaraldehyde
and 2% paraformeldehyde in PBS, then paraffin embedded. As one would
expect, we are having trouble trying to do any immunohistochemistry on the
tissue, cut in 8 um sections. We are currently attempting to do GFAP
staining without success. I have tried to 'break apart' the glutaraldehyde
bonds with a 1% Triton X solution for 10 min. This seemed to help a little
bit, but it is still not sufficient. I was wondering if anyone out there
has had any luck with staining tissue of this nature, or is it a lost cause?
Any suggestions would be appreciated! Thank you very much!
