生物活性

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[1][2].

IC50 Target

Kd: 11.7 pM (Kv1.3), 6.4 pM (Kv1.2) and 4.2 nM (Kv1.1)[1]

体内研究
(In Vivo)

Margatoxin (i.p.; 1 pmol/g) significantly decreases thiogycollate-induced leukocyte transmigration in the peritoneal cavity in 12-week-old C57BL6/J mice[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
