Figure 3

Panel (A) shows single channel recordings from HEK 293 cells transfected with either wild type AChR subunits or wild type AChR subunits plus εL221F-EGFP mutant AChR subunit. Prolonged bursts of openings are evident (downward deflections) stimulated by low concentration of ACh (100 nM). Panel (B) shows mEPC recordings from diaphragm muscle of mutant mice expressing εL221F-EGFP containing AChR (red trace). Endplate currents are prolonged in these mice as a result of the increased duration of AChR burst kinetics.
