      • Alomone Labs Agitoxin-1 inhibits KV1.3 channels heterologously expressed in Xenopus oocytes.
        Left: Sample current responses to 100 ms depolarization to 0 mV from holding potential of -100 mV, delivered every 10 seconds before (red) and during (black) application of 10 nM Agitoxin-1 (#RTA-150). Right: time course of amplitude inhibition. The effect of 10 and 50 nM Agitoxin-1 on KV1.3 current amplitude are shown. The horizontal bars indicate the periods of toxin perfusion.
      • Like Agitoxin-2, Agitoxin-1 is a potent blocker of the Shaker voltage-gated K+ channels as well as the mammalian homologues of Shaker.1
    Target KV1.3 channels
