Abstract
A technique for rapidly preparing a large number of paired and uniformly good quality frozen sections has been described in terms of specific procedures followed and apparatus required. Two innovations were noted: 1) a microtome chuck that allows precise alignment of two tissue blocks that are to be cut simultaneously, and 2) a heating tray for microslides that enables a controlled amount of heat to be applied to a small section of a slide that is subsequently used in "jump" mounting of two freshly cut sections.
