A method is presented for the rapid in vitro amplification of DNA sequences that flank a region of known sequence. The method uses the polymerase chain reaction (PCR), but it has the primers oriented in the reverse direction of the usual orientation. The template for the reverse primers is a restriction fragment that has been ligated upon itself to form a circle. This procedure of inverse PCR (IPCR) has many applications in molecular genetics, for example, the amplification and identification of sequences flanking transposable elements. In this paper we show the feasibility of IPCR by amplifying the sequences that flank an IS1 element in the genome of a natural isolate of Escherichia coli.
本文介绍了一种用于快速体外扩增已知序列区域侧翼DNA序列的方法。该方法使用聚合酶链反应（PCR），但其引物的方向与通常的方向相反。反向引物的模板是一个已自身连接形成环状的限制性片段。这种反向PCR（IPCR）方法在分子遗传学中有许多应用，例如，扩增和鉴定转座元件侧翼的序列。在本文中，我们通过扩增大肠杆菌自然分离株基因组中IS1元件侧翼的序列，展示了IPCR的可行性。
