After 12 to 14 days of incubation grids with mouse neurons were plunge frozen with a Vitrobot (Thermofisher Scientific, Mark IV) with a blot time of 3 s and a blot force of -10. Wait time and drain time were not used. Humidity was set to 100% at 4 degrees C. 4 ul undiluted 10 nm BSA gold tracer (Aurion) was added directly onto the grid prior to plunge freezing..
