Summary

Automatic Translation

Automatic Translation

Neuronal membrane trafficking dynamically controls plasma membrane protein availability and significantly impacts neurotransmission. To date, it has been challenging to measure neuronal endocytic trafficking in adult neurons. Here, we describe a highly effective, quantitative method to measure rapid changes in surface protein expression ex vivo in acute brain slices.
