Pre-amplification is a basis for numerous polymerase chain reaction (PCR) protocols but bears severe contamination risks due to handling of high-copy DNA samples. Therefore we developed a self-contained centrifugal microfluidic system comprising pre-stored reagents; it enables pre-amplification of specific DNA sequences prior to automated aliquoting and real-time PCR in a modified commercial thermocycler.
预扩增是许多聚合酶链反应(PCR)协议的基础,但由于处理高拷贝 DNA 样本,存在严重的污染风险。因此,我们开发了一种包含预存储试剂的独立离心微流控系统;它可以在修改后的商用热循环仪中进行自动等分和实时 PCR 之前,对特定 DNA 序列进行预扩增。
