近年来发展的酵母人工染色体ＹｅａｓｔＡｒｔｉｆｉｃａｌＣｈｒｏｍｏｓｏｍｅ（ＹＡＣ）可以克隆长至几百ｋｂ的ＤＮＡ片段。目前世界上已有一些ＹＡＣ文库，可以用ＰＣＲ方法或传统的原位杂交法来筛选高密度克隆膜以得到单一ＹＡＣ克隆，建立染色体特定区域的ＹＡＣ重...
The Yeast Artifical Chromosome (YAC), a yeast artificial chromosome developed in recent years, can clone DNA fragments up to several hundred kb in length. At present, there are some YAC libraries in the world that can screen high-density clone membrane by PCR method or traditional in situ hybridization method to get a single YAC clone and establish YAC heavy ...
