荧光蛋白已成为生物医学研究中不可或缺的成像工具。然而,荧光成像的持续发展需要具有针对新兴技术优化的附加颜色和性质的探针。在这里,我们总结了红移荧光蛋白的发展策略。我们讨论了基于荧光蛋白的光化学和蛋白质结构中发色团的位置的知识为基础的合理设计的可能性。我们认为诱变,蛋白质表达系统和仪器的高通量筛选,应产生先进的成像应用改进的荧光蛋白库设计的进展。
Fluorescent proteins have become indispensable imaging tools for biomedical research. continuing progress in fluorescence imaging, however, requires probes with additional colors and properties optimized for emerging techniques. Here we summarize strategies for development of red-shifted fluorescent proteins. We discuss possibilities for knowledge-based rational design based on the photochemistry of fluorescent proteins and the position of the chromophore in protein structure. We consider advances in library design by mutagenesis, protein expression systems and instrumentation for high-throughput screening that should yield improved fluorescent proteins for advanced imaging applications.
