Focal adhesion kinase (FAK) is a cytoplasmic non-receptor tyrosine kinase essential for a diverse set of cellular functions. Current methods for monitoring FAK activity in response to an extracellular stimulus lack spatiotemporal resolution and/or the ability to perform multiplex detection. Here we report on a novel approach to monitor the real-time kinase phosphorylation activity of FAK in live single cells by fluorescence lifetime imaging.
黏着斑激酶（FAK）是一种细胞质非受体酪氨酸激酶，对于多种细胞功能至关重要。目前用于监测细胞外刺激下 FAK 活性的方法缺乏时空分辨率和/或进行多重检测的能力。在这里，我们报告了一种通过荧光寿命成像实时监测活单个细胞中 FAK 激酶磷酸化活性的新方法。
