The method is just like the QuikChange site-directed mutagenesis method except for its special primer. This pair of primers is composed of a long primer and a short primer which is central overlapped.Both of the Tm of 5\'sequence in long primer and Tm of 3\'sequence in short primer are above 66℃.The Tm of short primer is almost half of that of long primer.It is convenient to perform insertion or substitution mutation of DNA fragments larger than 20bp,In addition,it is highly applicable in research about the deletion mutation of DNA fragments larger than 2000bp.

我们实验室一直在寻找一种简单高效的可以用于基因的删除、插入及替代突变的方法，通过大量研究和实验发现，可以使用一种基于反向PCR原理，使用全新的引物设计的突变方法——&COP&突变法，该方法采用与QuikChange点突变法相同的操作步骤，其策略是设计一对中心重合的引物，长引物的5\'端序列和3\'端序列的Tm值均不低于66℃，短引物Tm值约为长引物一半，且与长引物中心重合互补。

Here, Risk Assessment Code matrix method and runaway scenario analysis method were used to evaluate the thermal runaway criticality, and some reaction conditions were compared and analyzed as well. At last, based on the experimental results, the theoretical calculation was adopted to analyze the decomposition of nitration product and the electrophilic substitution mechanism of these nitration reactions. All these work are of important value for the correct evaluation of thermal risk and the decrease of chemical reaction runaway accidents.
