新的光纳米体成像技术可高精度地对活细胞中的蛋白质进行视觉化. New fluorescent nanobody imaging technology visualizes proteins in living cells with high precision.

艾伯特·爱因斯坦医学院和索尔克研究所的科学家开发了VIS-Fbs, 这是一种新的成像技术, 使用工程光纳米体可视化活细胞内的蛋白质. Scientists at the Albert Einstein College of Medicine and the Salk Institute have developed VIS-Fbs, a new imaging technology that uses engineered fluorescent nanobodies to visualize proteins inside living cells. 通过仅在与目标相连时发光, 该系统可大大减少背景噪声并允许实时多色追踪像小鼠和斑马鱼等生物中的蛋白质活动. By emitting light only when bound to targets, the system drastically reduces background noise and allows for real-time, multicolor tracking of protein activity in organisms like mice and zebrafish.
