For purposes of this chapter, however, we will limit our discussion almost exclusively to the epoxide sections, since these are the most commonly used resins for biological work. Any of the stains for these resins will work with much-reduced staining time on more water-miscible sections.

An excellent and concise source of information on ultramicrotomy is the booklet “Ultramicrotomy: Frequent Faults and Problems,” by Sitte (1981). A more

Support Films,otherwise fall through the openings in the grids. Support films are also used to cover grids with large open areas (e.g., 1 × 2 mm openings in slot grids), which can be used to view an entire 1-mm. section without obstruction from opaque grid bars. Finally, holey films can be prepared that are used
