title: [Preparation of isolated cells by alkaline dissociation of formalin fixed tissue].
abstract: A procedure is described for preparation of isolated cells by treating formaldehyde fixed tissues with a 50%-solution of KOH. This results in complete yield of cells from a variety of organs (liver, kidney, heart, spleen, etc.). The alkali-treated cells entirely retain their morphological and tinctorial peculiarities. It was shown that preparations derived from alkali-treated tissues were useful for a series of quantitative cytological and cytochemical techniques: cytofluorometric estimation of nuclear DNA; interferometric determination of dry cell mass; autoradiographic studies of nuclear DNA synthesis; cell number counts; evaluation of cell distribution according to the number of their nuclei; estimation of the mitotic index.
