How to track and trace a protein: Nanosensors monitor intracellular deliveries

(University of Basel) Researchers at the University of Basel's Biozentrum have developed a method for tracing the movement of proteins within the cell. They tagged proteins with tiny nanosensors, so-called nanobodies, which enable the scientists to live track and trace the proteins' pathway through the cell. The method described in the current issue of PNAS is suitable for a wide range of research purposes.
