- Alomone Labs δ-Dendrotoxin blocks KV1.1 channels expressed in Xenopus oocytes.A. Representative time course of δ-Dendrotoxin (#D-380) inhibition of KV1.1 current. Membrane potential was held at -100 mV, current was elicited by a 100 ms voltage ramp to +20 mV every 10 sec, and significantly inhibited by 0.5 nM δ-Dendrotoxin (green). B. Superimposed traces of KV1.1 current following application of control (black) and of 0.5 nM δ-Dendrotoxin (green), taken from the recording in A.
δ-Dendrotoxin is isolated from Dendroaspis angusticeps1 snake venom by modification of the procedures of Harvey2 and Benishin1 and purified to homogeneity.
δ-Dendrotoxin blocks KV1.1 channels (IC50 = 0.1 nM,3 for review see 4). The toxin was shown to also block KV1.6 (IC50= 23 nM).4 In addition δ-Dendrotoxin blocks ROMK1 inward rectifier K+ channels with Kd of 150 nM.3
δ-Dendrotoxin (#D-380) is a highly pure, natural, and biologically active peptide toxin.
