Re: help for IHC and alcoholic fixation
We are working in a basic research project using quite
a wide range of antibodies for bovine tissues. We routinely
prepare most tissue samples in three different fixatives:
routine paraformaldehyde fixation, carnoy's fixative and
simply 100% ethanol. Ethanol fixative is performed by first keeping
the tissue samples in 100% ethanol for a few hours at +4C,
then transferring the (small) container to -20C, fixing
there for 4 days, then processing for routine paraffin
There of course are the common ethanol fixation problems,
but immunohistochemistry works generally pretty well.
That is, I'd say most of our antibodies work without
any special pretreatments. These include both membrane
and cytoplasmic antigens. I can provide a more comprehensive
list if necessary - but as it's bovine specific it's probably
not of direct use.
