Transformation-associated recombination (TAR) cloning allows selective isolation of full-length genes and genomic loci as large circular Yeast Artificial Chromosomes (YACs) in yeast. The method has a broad application for structural and functional genomics, long-range haplotyping, characterization of chromosomal rearrangements, and evolutionary studies. In this paper, we describe a basic protocol for gene isolation by TAR as well as a method to convert TAR isolates into Bacterial Artificial Chromosomes (BACs) using a retrofitting vector. The retrofitting vector contains a 3' HPRT-loxP cassette to allow subsequent gene loading into a unique loxP site of the HAC-based (Human Artificial Chromosome) gene delivery vector. The benefit of combining the TAR gene cloning technology with the HAC gene delivery system for gene expression studies is discussed.
转化相关重组(TAR)克隆技术可在酵母中作为大型环状酵母人工染色体(YAC)选择性分离全长基因和基因组位点。该方法在结构和功能基因组学、长程单倍型分析、染色体重排特征研究及进化研究等方面有广泛应用。本文描述了通过TAR进行基因分离的基本方案,以及使用改造载体将TAR分离物转化为细菌人工染色体(BAC)的方法。该改造载体包含一个3'HPRT-loxP盒,以便随后将基因加载到基于HAC(人类人工染色体)的基因递送载体的独特loxP位点。讨论了将TAR基因克隆技术与HAC基因递送系统相结合用于基因表达研究的益处。
