Reduced EGTA sensitivity in brp69, sytKD. (A) Focally recorded, averaged EPSCs from sytKD (gray) and brp69, sytKD (light green) NMJs under control conditions and after incubation with 100 μM EGTA-AM for 10 min (+EGTA). (B) Summary bar graph of EPSC amplitudes without (–) or with (+) EGTA-AM in both genotypes.
