Cutting Unfixed Frozen Sections for Fluorescence Antibody Studies

Abstract

A simplified method of section cutting, dispensing with guide attachment on microtome blade, and suitable for serial sections of unfixed frozen tissue of 4μ is described. Essential features are low temperature maintenance (—13°C), critical angle of knife and moistening of slides in cold alcohol or isopentane. This method has been found suitable for fluorescence antibody studies where maintenance of low temperatures is necessary.
