In the first example of site-directed spin-labeling of unmodified RNA, a pyrrolidine-nitroxide derivative of tetramethylrosamine (TMR) was shown to bind with high affinity to the malachite green (MG) aptamer, as determined by continuous-wave (CW) electron paramagnetic resonance (EPR), pulsed electron-electron double resonance (PELDOR) and fluorescence spectroscopies.
在未经修饰的 RNA 定点自旋标记的第一个实例中,通过连续波(CW)电子顺磁共振(EPR)、脉冲电子-电子双共振(PELDOR)和荧光光谱学测定,表明四甲基罗丹明(TMR)的吡咯烷-氮氧化物衍生物与孔雀石绿(MG)适体具有高亲和力。
