Identification of a para-axon initial segment (AIS). Triple immunostaining of Peripherin (A, E), ankyrin G (AnkG) (B, F) and contactin-associated protein (Caspr) (C, G) (merged in (D, H)) showing a Caspr-positive segment at the distal end of the AIS (D, H). (E-H) Magnified views of the frames in (A-D). Brackets indicate the AnkG+ AIS and the Caspr+ para-AIS. Scale bar = 10 μm (A-D), 2 μm (E-H).
