Chlorotoxin vs Conotoxin

Chlorotoxin vs Conotoxin — mechanism, half-life, dosing, and research status compared. Which is right for your protocol?

Chlorotoxin
Venom Peptide

Chlorotoxin is a 36-residue peptide toxin from the deathstalker scorpion (Leiurus quinquestriatus). Originally identified as a chloride channel blocker, it was discovered to bind selectively and with high affinity to glioma cells but not normal brain tissue, through interaction w...

Conotoxin
Venom Peptide

Conotoxins (conopeptides) are a diverse superfamily of small, disulfide-rich peptide toxins produced by predatory cone snails (Conus species). With >10,000 predicted sequences across ~700 Conus species, conotoxins are an extraordinary reservoir of pharmacologically selective tool...
