Abstract

The ultrastructure of freeze-substituted Malpighian tubule cells of German cockroach after rapid freezing was compared to that fixed with conventional chemical fixation. As results, freeze-substitution proved to be the superior technique revealing much more structural details of the tissue cells. Especially, all kinds of membrane structures including infoldings, microfilament, microtubules and ribosomes were best preserved in this material.
