Fig. 8: Electron immunomicroscopic localization of Hax-1 in Purkinje cells (PC) using diaminobenzidine labeling to localize immunoreactivity.

a, b Immunostaining detected at the plasma membrane of wild-type animals. c, d Hax-1 immunoreactivity at sites where mitochondria are apposed to the plasma membrane in wild-type animals. e Hax-1 on endoplasmic reticulum (wild-type mice). f Hax-1-immunoreactive protrusions at the soma of a neuron from a wild-type animal. g Hax-1 at the plasma membrane in G592R Kv3.3 mice. h Mitochondrial/plasma membrane Hax-1 immunoreactivity in G592R Kv3.3 mice. i and j Hax-1 on endoplasmic reticulum in G592R Kv3.3 mice. k and l Examples of multivesicular bodies with internal Hax-1 immunoreactivity in G592R Kv3.3 animals. Hax-1 immunostaining is representative of 40 and 32 images taken from sections of three wild type and three G592R Kv3.3 mice, respectively. Scale bars for all figures, 500 nm.
