Re: alcohol-based fixation for PCNA detection
We have used Histochoice fixative with good success in paraffin-embedded sheep tissues when staining for PCNA.

I have recently read that PCNA is found in two fractions in cells: a fraction associated with the chromosomes and a fraction free in the nucleoplasm. The latter can be "eliminated" by using an alcohol-based fixative, prior to immunohistochemical detection of PCNA.
Does anybody have any suggestions on which fixative would be best. I have been thinking of methacarn. Any suggestions or comments on the quality of morphology when using alcohol-based fixatives?
