Isolation of tityustoxin-sensitive currents in dissociated hippocampal neurons. A, The tityustoxin (100 nm) sensitivity of Kv1.2 and various Kv1.2-containing heteromeric channels was measured for channels expressed in LM cells. B, K⁺ currents were measured from dissociated hippocampal neurons in the presence and absence of 100 or 300 nm tityustoxin to isolate tityustoxin-sensitive currents by subtraction.
