摘要
基因组序列的功能分析以及代谢途径的构建改造等都需要克隆目的 DNA。获得大片段DNA序列的方法有构建和筛选基因文库,PCR扩增,体外大片段DNA合成和组装等,但体内重组直接克隆的方法在操作、克隆长片段和应用等方面更具优势。介绍了Red/ET重组介导的大片段DNA体内直接克隆的主要方法及其应用。
Cloning of interest DNA is necessary for functional analysis of genome sequences and research on metabolically engineered pathways of modern producer strains. Methods to precisely clone large DNA fragments include library constructing and screening, PCR amplification and various different DNA assembly methods in vitro. In addition, direct cloning by homologous recombination in vivo has more advantages in the cloning and engineering of long DNA sequences. The main methods of direct cloning of large DNA fragments in vivo via Red/ ET recombination system and its applications were introduced.
