A one-step procedure is presented for simultaneous measurement of cell number and DNA content in cultured plant cells by flow cytometry. In order to obtain nuclei representative of the growth stadium of the culture and of all phases of the cell cycle, cells were carefully sampled and immediately fixed. Next, nuclei were isolated by enzymatic and mechanical maceration, and stained with a DNA-specific fluorescent dye. In the resultant preparation, cells can be counted at relative ease by means of… CONTINUE READING
