Cells were examined using a Bio-Rad MRC 600 confocal microscope with excitation wavelengths appropriate for Alexa 488 (488 nm) and Alexa 594 (594 nm). mamba snake toxin dendrotoxin-K (DTX-K) clogged the Kv1.1 outward current when indicated like a homotetrameric complex (EC50 = 0.34 nm). Additional Kv channels were insensitive to Continue Reading
