Figure 4

Voltage-clamp recordings were performed on Xenopus oocytes expressing NaV1.4 as describe in Materials and Methods. Representative sodium currents recorded in the absence of toxin (control traces, gray) and following ~30 min exposure to 1μM BuIIIA, BuIIIB, and BuIIIC (black traces). Each trace represents the average of 5 responses.
