Cell-Free System
| Definition: |
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) |
| Notes: |
for study of subcellular fractions; not for micro-organisms; NIM; use A 11 qualif discreetly |
