KV1 (Shaker-Relared Potassium Channels) - Block of Mutated Channel

application shaker 2icon pap   Port-a-Patch data and applications: 
Data were kindly provided by Dr. Kenton Swartz, NIH, Bethesda, USA.

Block of Shaker-IR by Agitoxin2. Shown are current recordings from HEK293 transiently expressing Shaker-IR. Currents were elicited by a 500 ms step to +50 mV from a holding potential of -80 mV. K+ gradients are the same as for the IV curve experiment shown above. 200 nM Agitoxin2 almost fully blocks the Shaker K+ current.
