Molecular cloning is one of the most fundamental technologies in molecular biology, and has been critical for driving biotechnological advances. In this study, we have developed a novel method for standardized molecular cloning. The cloning technique known as "Nimble Cloning" uses the restriction enzyme, I, in combination with the T5 exonuclease, to linearize the vector and generate 3'-overhangs simultaneously. Both PCR products and plasmids can be used for the cloning reaction in the Nimble Cloning system. The cloning system is highly efficient, suitable for gene expression in both prokaryotic and eukaryotic expression systems, and enables the reuse of DNA fragments or plasmid entry clones. Nimble Cloning is applicable for the cloning of single or multiple fragments, as well as multi-site cloning. Due also to its simplicity and versatility, the cloning method has great potential for the modular assembly of DNA constructs.
分子克隆是分子生物学中最基本的技术之一,对推动生物技术进步至关重要。在本研究中,我们开发了一种用于标准化分子克隆的新方法。被称为“灵活克隆”的克隆技术使用限制性内切酶I与T5核酸外切酶相结合,使载体线性化并同时产生3'端突出端。PCR产物和质粒均可用于灵活克隆系统中的克隆反应。该克隆系统效率高,适用于原核和真核表达系统中的基因表达,并能重复使用DNA片段或质粒入门克隆。灵活克隆适用于单个或多个片段的克隆以及多位点克隆。由于其简单性和通用性,该克隆方法在DNA构建体的模块化组装方面具有巨大潜力。
