      • β-Dendrotoxin
        Alomone Labs β-Dendrotoxin inhibits cloned KV1.1 and KV1.2 channel currents heterologously expressed in Xenopus oocytes.
        KV1.1 (left, in 2 mM K+) and KV1.2 (right, in 5 mM K+) channel currents, elicited by 200 ms depolarization from holding potential of -100 mV to +20 mV, before and during application of 100 nM β-Dendrotoxin (#B-360). 62% (n = 4) of the KV1.1 and 74% (n = 4) of the KV1.2 channels were inhibited by 100 nM β-Dendrotoxin, respectively.
