A Quick-Freeze Method for Making Smear Slides Permanent

Abstract

AbstractMany types of smear slides can be made permanent rapidly and effectively by substituting for the usual dehydration series a single-step process of freezing the slide on a block of dry ice, placing it immediately in 95% or absolute alcohol, and then mounting it. Advantages of the technic are its speed, the ease of separation of cover slip from slide with a minimum loss of cells, and the superiority of the resulting permanent slides.
