Seeing is Believing: New Probes Reveal Proteins Inside Living Cells with Unprecedented Clarity

Developed by Albert Einstein College of Medicine and the Salk Institute for Biological Studies, Multicolor Imaging Technology Lets Researchers Track Proteins and Cellular Activity with Exceptional Precision and Minimal Background

Antigen‑Stabilized Nanobody Probes Enable On‑Demand, Multicolor Protein Imaging

Fluorescent probes have reshaped how biologists study living systems, making it possible to watch viruses invade cells, follow the cell’s internal waste‑disposal machinery, and track the signaling events that fuel tumor growth. Yet even with decades of innovation, a fundamental limitation has persisted: most fluorescent nanobody probes glow whether or not they are bound to their targets. That constant background haze can blur the very molecular …
