Red-shifted fluorescent indicators for magnesium were developed by incorporation of sulfur or selenium in the azole moiety of ‘fura’ fluorophores. Single atom replacement in the acceptor of these ITC probes affords longer excitation and emission wavelengths as well as greater separation between excitation bands, valuable for ratiometric intracellular Mg2+ imaging.
通过在“fura”荧光团的吡唑部分引入硫或硒,开发了镁离子的红移荧光指示剂。在这些ITC探针的受体中进行单原子替换,可以获得更长的激发和发射波长,以及更大的激发带间距,这对于细胞内Mg2+比率成像非常有价值。
