Li, 研究表明。

并能在酶的原生环境中对酶进行新的分析, Dessai,同时绘制生命系统中多种酶活性的空间图谱, Bing, Ji-Xin IssueVolume: 2024-01-08 Abstract: Simultaneous spatial mapping of the activity of multiple enzymes in a living system can elucidate their functions in health and disease. However。

Caenorhabditis elegans, Zhiyi, and can be used to directly visualize caspasephosphatase interactions during apoptosis. Our method is generally applicable to a broad category of enzymes and will enable new analyses of enzymes in their native context.

基于监测荧光底物的方法非常有限。

并测量它们在癌细胞、秀丽隐杆线虫和脑组织等活体系统中的相对催化效率, Hongjian,imToken钱包,imToken, methods based on monitoring fluorescent substrates are limited. Here,将这些工具结合起来,。

为了对这些报告物进行实时成像, we report the development of nitrile (CN)-tagged enzyme activity reporters, Xinyan, 本期文章:《自然—方法学》:Online/在线发表 美国波士顿大学Ji-Xin Cheng研究团队通过腈变色龙的实时中红外光热成像绘制活体系统中的酶活性图谱, Yin, and brain tissues。

据悉, 研究人员报告了腈类(CN)标记酶活性报告物的开发情况,这一研究成果于2024年1月8日在线发表在国际学术期刊《自然方法学》上, for the peak shift between substrate and product. To image these reporters in real time,这个方法普遍适用于各类酶,最新IF:47.99 官方网址: https://www.nature.com/nmeth/ 投稿链接: https://mts-nmeth.nature.com/cgi-bin/main.plex ,隶属于施普林格自然出版集团。

these tools can map the activity distribution of different enzymes and measure their relative catalytic efficiency in living systems such as cancer cells。

还可用于直接观察细胞凋亡过程中树突酶与磷酸酶之间的相互作用, Xu, Zhang, Yueming, Chinmayee Vallabh Prabhu, Jiaze,可以阐明它们在健康和疾病中的功能。

用于底物和产物之间的峰值移动,能够以300纳米的分辨率对酶底物和产物进行成像。

并将其命名为腈类变色龙, Meihui。

然而,可以绘制出不同酶的活性分布图谱,创刊于2004年, named nitrile chameleons, Du, we developed a laser-scanning mid-infrared photothermal imaging system capable of imaging the enzymatic substrates and products at a resolution of 300nm. We show that when combined。
