Figure 3. Normal Localization of NEFL at Motor End Plates in Affected Muscle.
A and B, Indirect immunofluorescence shows similar localization of NEFL protein in transverse sections of control (A) and patient 20-2 (B) skeletal muscle biopsy specimens. C-E, Shown is double-label indirect immunofluorescence of a longitudinal section of myofiber from patient 20-2 stained for NEFL (green in C) and a-bungarotoxin (red in D). The merged image in E identifies NEFL-positive structures as motor end plates (scale bars are 50μm).
