Fig. 4. Distribution of MYH13 in global and orbital layers of rabbit extraocular
muscle (EOM). (A) The specificity of EO-1 was established by staining sections
from control muscles that express the other skeletal and cardiac MyHC isoforms
as described in text: adductor magnus (Add. Mag.), semitendinosus (ST),
Diaphragm and fetal muscle (gest. day 27). (B) In the central region of EOM
containing the endplate band, EO-1 stains most fibers in the orbital region
near the top of the section, as well as many fibers in the global layer in the
lower portion of the section. Scale bar, 200 µm.
