Fluorescence quenching nitrodiarylethene analogs are useful in oligonucleotide conjugates and probes. These analogs, whose absorption spectra are substantially blue-shifted relatively to emission spectra of common fluorophores (such as fluorescein), do not need to rely on spectral overlap of quencher absorbance and fluorophore's emission for their quenching abilities. The oligonucleotide-quencher conjugates may be used in detection methods for nucleic acid targets.
荧光淬灭硝基二叔
丁烯类似物可用于寡核苷酸共轭物和探针。与普通荧光团(如
荧光素)的发射光谱相比,这些类似物的吸收光谱基本上是蓝移的,因此其淬灭能力无需依赖淬灭剂吸收光谱与荧光团发射光谱的重叠。寡核苷酸-淬灭剂共轭物可用于核酸靶标的检测方法。
