Fig. 2. Delayed occurrence of AChR clustering in the absence of the
-subunit. (A-F) Whole-mount diaphragm muscles
(E16.5-E18.5) labeled with Texas Red-conjugated
-bungarotoxin. AChR
clusters were detected in the
-/- muscles (arrowheads in
D-F), although they were less numerous and appeared dimmer than those observed
in the wild-type muscle (arrowheads in A-C). (G) Comparison of the
fluorescence intensity (mean gray value), area, perimeter and Feret's diameter
(the length of the greatest axis) of individual AChR clusters in the
-/- muscles with those of the wild-type muscles.
