Effects of heated and non-heated verrucotoxin (VTX) on L-type Ca2+ currents (ICa(L)). ICa(L) was elicited by 500 ms depolarizing pulses from −40 to 0 mV every 10 s. The current amplitude was measured as the difference between the peak of ICa(L) and the current at the end of the pulse, and plotted against the experimental time.
