found to display distinct and specific fluorescence enhancement upon binding to parallel G-quadruplexes. Such a sensitive and topology-specific probe is able to light up without affecting the topology or thermal stability of the G-quadruplex sample. Thus, these advantages distinguish IZCM-1 from other G-quadruplex probes.
已经发现一种新颖的2,4,5-三芳基取代的咪唑(IZCM-1)在与平行的G-四链体结合后显示出独特的特异性荧光增强作用。这种灵敏且特定于拓扑的探针能够点亮,而不会影响G-四链体样品的拓扑或热稳定性。因此,这些优点将IZCM-1与其他G四联探针区分开来。
