Hazard Information | Back Directory | [Biochem/physiol Actions]
Margatoxin is an α-KTx toxin, which is majorly used in ion channel research. It is a 39-amino acid peptide, which is a specific K(V)1.3 channel voltage-dependent K+ channel blocker. Margatoxin is an immunosuppressant that is isolated from the venom of the scorpion Centruroides margaritatus. | [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]. | [storage]
