Summary: The staining ability of uranyl acetate(UA)solution was examined by dipping100grids with ultrathin sections consecutively in a single drop of this solution using freeze-substituted and epoxy-resin-embedded yeast cells. No decrease in the staining ability was observed. Thus, the repeated use of UA solution is recommended, which should contribute to not only the economical use of UA solution but also the protection of the environment by reducing the amount of undesirable waste.
