Abstract

In-cell DEER (in-cell double electron electron resonance) is applied to investigate quadruplex formation of the human telomeric repeat d[AGGG(TTAGGG)(3)]. The initially unfolded DNA sequence forms a mixture of different quadruplex topologies upon injection into living cells. In addition, time-dependent distance measurements are carried out to monitor quadruplex folding.

摘要

在细胞内双电子电子共振(in-cell double electron electron resonance,in-cell DEER)被应用于研究人类端粒重复 d[AGGG(TTAGGG)(3)]的四链体形成。该初始未折叠的 DNA 序列在注入活细胞后形成不同四链体拓扑结构的混合物。此外,还进行了时间依赖性距离测量以监测四链体折叠。
