An isothermal amplification circuit for specific DNA molecules was implemented in giant unilamellar vesicles. Using this circuit, over 5000-fold amplification of output DNAs was achieved, and the amplification behaviour depended on the concentration of input signal DNAs in a cell-sized compartment. Moreover, initiation of the amplification by photo-stimulation was demonstrated.
在巨大的单层囊泡中实现了特定 DNA 分子的等温扩增电路。利用该电路,实现了输出 DNA 的 5000 倍以上的扩增,并且扩增行为取决于细胞大小隔室中输入信号 DNA 的浓度。此外,还证明了通过光刺激引发扩增。
