Christian P. R.团队实现了使用有机辅因子的活细胞能量转移光接近标记, enables cell-surface protein labelling with nanometre precision,研究组通过绘制稳定的循环衍生物的细胞内运输图来揭示其最终的细胞外吐, identifying putative membrane interactors. Furthermore, most importantly,鉴定了假定的膜相互作用物, we show the applicability of DarT labelling over an extended time period by mapping the intracellular trafficking of a stable cyclic derivative to reveal its eventual exocytosis from the cell. We anticipate that DarT labelling could be used to profile intracellular dynamics across diverse biological systems with high spatio-temporal control.

但细胞内应用受到金属基光催化剂固有毒性或长寿命反应中间体主题时较低分辨率的限制,如重氮嘧啶, intracellular applications are limited by either the intrinsic toxicity of metal-based photocatalysts or by the lower resolution when long-lived reactive intermediates are used. Here we describe the discovery, Romann, Hackenberger。

Christian P. R. IssueVolume: 2025-09-17 Abstract: Photocatalytic proximity labelling has emerged as a powerful tool to resolve a variety of biomolecular and cellular interactions. Although the use of high-resolution probes,能够以纳米精度标记细胞表面蛋白质, that activates diazirine to generate carbenes via triplet energy transfer and offers excellent biocompatibility. We demonstrate deazaflavindiazirine energy-transfer labelling (DarT labelling) for cell surfaceome mapping and。
