My antibody didn't work at all. I have mouse brains, 30 um cryosectioned, and tried different concentrations of tween, as well as both formamide and SSC treatment to no avail.
Hi Tatyana, I'm assuming you are working with 4% paraformaldehyde perfused tissue? If so, I have had good luck with a rabbit anti-Ki67 antibody from vector labs in a free floating protocol for mouse tissue. You can find the protocol in the paper I'm attaching. The protocol is under "immunohistochemistry" and some images of the resulting stain are attached separately. Hope this is helpful!

I am looking for immune cells infiltration in liver tissues via IHC-P and then look for co-localization in free floating sections by Zeiss 710. I note that if tissue are fixed more than 48hrs in 4%PFA, the antigenicity of immuno-cell types is lost.
Therefore I would like to seek your opinion on post fixation (of tissues to be paraffin embedded) and particularly Fixation and post-fixation of tissue (for free floating sections) What could be the possible fixatives in above cases and for how long antigenicity could be preserved?
