Chlorotoxin

Catalog No.: A13933
Antitumor Agent
Chlorotoxin is a 36 amino acid peptide derived from the venom of the Israeli scorpion, Leiurus quinquestriatus, known for its antitumor properties. By functioning as a chloride channel blocker, Chlorotoxin inhibits the proliferation of cancer cells and modulates ion channel activity. This compound is valuable for cancer research, particularly in studies investigating tumor biology and the development of targeted therapies.
