Crotamine (TFA)

• UNSPSC Description:

  Crotamine TFA is a Na+ channel modulator. Crotamine is a 42 amino acid toxin cross-linked by three disulfide bridges. Crotamine has analgesic activity. Crotamine also interacts with lipid membranes and shows myonecrotic activity. Crotamine can be isolated from Crotalus durissus terrificus venom[1][2].
