体外翻译系统又称无细胞蛋白质合成系统 ,是分子生物学中一种常规的表达系统。该系统可用于蛋白质快速分析鉴定 ,基因转录和翻译的调控机理的研究以及分子间的相互作用的研究 ,如蛋白质和蛋白质的相互作用 ,蛋白质与 DNA的相互作用 ,蛋白质与 RNA的相互作用等 In vitro translation system, also known as cell-free protein synthesis system, is a routine expression system in molecular biology. The system can be used for the rapid identification of proteins, the study of the regulatory mechanisms of gene transcription and translation, and the intermolecular interactions such as protein-protein interaction, protein-DNA interaction, protein-RNA interaction
