Margatoxin
Based on 1 publication(s) in Google Scholar
Margatoxin, an alpha-KTx scorpion toxin, is a high affinity inhibitor of Kv1.3 (Kd=11.7 pM). Margatoxin inhibits the Kv1.2 (Kd=6.4 pM) and Kv1.1 (Kd=4.2 nM). Margatoxin, a 39 amino-acid-long peptide, is isolated from the venom of the scorpion Centruroides margaritatus and widely used in ion channel research.

Two-electrode voltage clamp in Xenopus oocytes
Two-electrode voltage clamp measures whole-oocyte membrane current from Xenopus oocytes expressing exogenous ion channels, receptors, or transporters; one intracellular microelectrode senses membrane voltage, and the second injects current so the amplifier can hold the membrane at command voltages while recording the compensating current as the functional readout. The method is suited to Xenopus oocytes because their large size supports microinjection and intracellular electrode impalement, but the large membrane area can limit voltage-clamp speed and accuracy, especially for large or fast currents.
