Iberiotoxin

• UNSPSC Description:

  Iberiotoxin is a toxin isolated from Buthus tamulus scorpion venom. Iberiotoxin is a selective high conductance high conductance Ca2+-activated K+ channel inhibitor with a Kd of ~1 nM. Iberiotoxin does not block other types of voltage-dependent ion channels[1][2][3].
