T-type Ca²⁺ Channel Blocker

Kurtoxin, a very interesting channel blocker, from T-Type, is described as a complex peptide built of 63 amino acids and four disulfide bridges. Kurtoxin inhibits partially N- and L-type ion channels as well as P-Type and T-Type ion channels and binds to voltage-gated Na⁺ channels and slows their inactivation. Our peptide toxin Kurtoxin was originally isolated from the venom of the african scorpion Parabuthus transvaalicus and is a synthetic peptide, carefully manufactured from Peptide Institute, Inc.
