It is the first time that no additional anode was adopted in the magnetic macroparticles filter. At the same time the auto-re-igniting system was designed for vacuum cathodic arc deposition instrument. It ignites the arc with an electronic component with high voltage and can auto distinguish weather the arc dies out or is on during the deposition via a main power supply feedback unit. The energy for igniting the arc is very less and thus can successfully prevent the film being contaminated.

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。
