我们开发了一种增强型绿色荧光素酶(ELuc)作为生物发光成像(BLI)探针。ELuc在哺乳动物细胞中显示的光信号比最广泛使用的荧光素酶报告基因萤火虫荧光素酶(FLuc)强10倍以上。我们发现,ELuc在原代细胞和组织中产生强烈的光信号,并且它能够在单细胞水平上以高时间分辨率可视化基因表达。此外,我们成功地成像核质穿梭importin α通过融合的ELuc在细胞内水平。这些结果表明,使用ELuc允许BLI时空分辨率远远大于FLuc提供的。
We developed an enhanced green-emitting luciferase (ELuc) to be used as a bioluminescence imaging (BLI) probe. ELuc exhibits a light signal in mammalian cells that is over 10-fold stronger than that of the firefly luciferase (FLuc), which is the most widely used luciferase reporter gene. We showed that ELuc produces a strong light signal in primary cells and tissues and that it enables the visualization of gene expression with high temporal resolution at the single-cell level. Moreover, we successfully imaged the nucleocytoplasmic shuttling of importin α by fusing ELuc at the intracellular level. These results demonstrate that the use of ELuc allows a BLI spatiotemporal resolution far greater than that provided by FLuc.
