light‐programmable, cell‐permeable reporter deliverable simultaneously to many cells. The reporter's ability to act as a substrate for Akt, a key oncogenic kinase, was masked by a 2‐4,5‐dimethoxy 2‐nitrobenzyl (DMNB) moiety. Upon exposure to ultraviolet light and release of the masking moiety, the substrate sequence enabled programmable reaction times within the cell cytoplasm. When coupled to automated single‐cell
评估小型临床样品中致癌激酶活性的工具具有指导肿瘤学精密医学的能力。现有平台已经证明了对蛋白激酶活性的深刻见解,但是这些技术不适合研究大量原代人细胞中的激酶行为。为了解决这些局限性,我们开发了一种集成分析系统,该系统利用可同时传输到许多细胞的光可编程,可渗透细胞的报告分子。报道者充当关键致癌激酶Akt的底物的能力被2-4,5-二甲氧基2-硝基苄基(DMNB)部分掩盖。暴露于紫外线并释放掩蔽部分后,底物序列可实现细胞质内可编程的反应时间。
