Immunogold localization of dynamin at coated endocytic structures trapped after perturbation of l-EHD. A, Examples of coated pits with long necks decorated with dynamin immunogold labeling in axons stimulated after microinjection of l-EHD antibodies. Scale bar, 0.2 μm. B, Regression analysis of dynamin labeling and length of coated pits in EHD antibody-injected axons (R2 = 0.43, n = 45, 0.05 < p < 0.01, Pearson's correlation coefficient).
