alcohol-based fixation for PCNA detection
Hello everybody,
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?
Thanks.
