  rdf:value "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."@en, "Extracto celular fraccionado que mantiene una función biológica. Una fracción subcelular aislada mediante ultracentrifugación u otra técnica de separación primero se debe aislar para que un proceso se pueda estudiar sin las demás reacciones colaterales complejas que se producen en una célula. En consecuencia, el sistema libre de células es muy utilizado en biología."@es ;
