title: Microwave fixation method for cytochemistry. For conventional electron microscopy, enzymo-immunocytochemistry, autoradiography elemental distribution studies and staining methods.
abstract: More than a decade ago, we introduced a microprocessed household microwave oven for microwave-stimulated fixation. In this paper we present an overview of our experience. We have introduced the use of tannic acid (TA, 0.1%), which is very effective for fixing soluble peptides or proteins, except in the case of enzymo-cytochemistry. In the latter case, a combination of TA with aldehyde in the microwave-fixation step brings perfect fixation, but inactivation of the enzymes and their enzymatic activities.
