The company is initially concentrating on biofilms that Lu says can corrode water pipes and block heat transfer in heating and cooling systems, decreasing energy efficiency by up to 80 percent.
The reactions are typically carried out on a regulated heatingblock, or PCR machine, and consist of 30-35 cycles of repeated amplification of all the DNA present.
这一反应通常是在一可调控的温箱中或PCR仪中进行，对所有的DNA进行30到35个循环扩增。
