β-adducin is enriched in myelinated axons at paranodes and juxtaparanodes. A, Immunostaining of rat optic (A) and sciatic nerves (B) for β-adducin and other node associated proteins (Na+ channels, caspr, Kv1.2, and βII spectrin). C, Immunostaining of developing rat sciatic nerve for β-adducin and the indicated node-associated proteins. Scale bars, 10 μm; the scale bar in B also applies to the panels shown in C.
