Kinetics of transport of 125I-tetanus toxin C fragment through intracellular compartments in Mel JuSo cells transfected with mIgG. Cells were allowed to internalize 125I-tetanus toxin C fragment for 5 min, followed by a chase for the times indicated in the different panels. Membranes were prepared and fractionated by sucrose density centrifugation (a) and organelle electrophoresis (b and c) for the times indicated.
