title: [A simple method of preparing permanent squash preparations using cellophane].
abstract: A technique to prepare permanent squashed preparations of cell nuclei and chromosomes is proposed. Fix a piece of material on the slide with acetic alcohol (1:3), macerate with a 45% acetic acid, cover with hydrophilic cellophane previously soaked in a 45% acetic acid and then with a cover slip and filter paper to squash finally as it is routinely performed. After that soak off the cover slip with alcohol, post-fix the squashed preparation together with cellophane in alcohol for 5-10 min, unstick the cellophane, pass the preparation through alcohol once again and dry it. The subsequent treatment of the squashed preparation depends on the purpose of investigation. The slide may be tinctured overlaid with photoemulsion for autoradiography, or processed by different ways.
