[主題詞] Cell-Free System
[英文釋義] A fractionated cell extract that maintains a biological function. A subcellular fraction isolated by ultracentrifugation or other separation techniques must first be isolated so that a process can be studied free from all of the complex side reactions that occur in a cell. The cell-free system is therefore widely used in cell biology. (From Alberts et al.,Molecular Biology of the Cell,2d ed,p166)
