Visualization and cleavage of DNA using fluorescence and ultrasonication

合成了各种不对称的吲哚马来酰亚胺，并对其光学性质进行了研究。一些吲哚马来酰亚胺具有较大的斯托克斯位移和最大荧光发射波长，其波长超过550 nm。在双链DNA存在下，测量了吲哚马来酰亚胺的荧光。在双链DNA存在下，含有N-甲基喹啉的吲哚基马来酰亚胺的荧光强度增强。

Various unsymmetric indolylmaleimides were synthesized and the optical propertywas clarified. Some indolylmaleimides have large Stokes shifts and fluorescence emission maximawavelengths of more than 550 nm. The fluorescence of indolylmaleimides was measured in the presence of double strand DNA. The fluorescence intensities of indolylmaleimides having N-methyl quinoline increased in the presence of double strand DNA.
