Re: Woodchuck tissue in Millonigs fixative
|From:||Gayle Callis <firstname.lastname@example.org>|
We had better luck with Trumps 4% gluteraldehyde/4% formaldehyde in
Sorensons Phosphate buffer, pH 7 to 7.4. We processed this the same as any
paraffin method for animal tissues. Tissues stored in fixative were good
for a year or so on shelf for EM. EM results were far better than with
modified Millonigs buffered formalin. It can be shipped to you in
fixative, stored at RT on shelf until used.
You can process in paraffin up to 1 hour per station. For EM, tissue could
be minced, rinsed with buffer and processed into epoxy of choice.
