RE: alternative fixation/processing schedules for sensitive antig ens
I tried that fixative a few years ago with mice and all thought that the
morphology was inferior to formalin. Our solution was to do perfusion with
NBF followed by a short post fix, 4-12 hours, then sucrose protect and
frozen sections. Morphology was good and antigenicity was fine for what we
were doing. Cynthia Favara

Subject: alternative fixation/processing schedules for sensitive
Has anyone out there tried the Zinc Acetate/Zinc chloride fixation method
for fixation-sensitive antigens? This fixation method is followed by
paraffin processing. Also, has anyone tried the AmeX (acetone-methyl
benzoate-xylene) tissue processing method?
I am interested in alternative fixation/processing schedules for sensitive
antigens. Antigen retrieval methods are not an option and frozen sections,
while acceptable, do not always provide excellent morphology.
Thanks for the advice!
