Descrizione

Descrizione generale

Lipid-soluble polyether marine toxin produced by the red tide dinoflagellate, Ptychodiscus brevis, found along the Gulf Coast of Florida. Voltage-dependent Na⁺ channel activator that causes contractile paralysis in animal models by binding to a unique site on these channels. The excitatory action of brevetoxins on nerve and muscle membranes is responsible for a wide spectrum of the toxic effects, including massive transmitter release from nerve endings, muscle fasciculations, and ventricular fibrillation. The toxin does not bind to either tetrodotoxin or aconitine/veratridine sites.

Azioni biochim/fisiol

Primary Target
Voltage-dependent Na+ channel activator

Attenzione

Toxicity: Highly Toxic (H)

Ricostituzione

Following reconstitution, aliquot, purge with inert gas and freeze (-20°C). Stock solutions are stable for up to 6 months at -20°C. Store stock solutions in glass vials; brevetoxin will stick to plastic. Use PTFE or silicon pipette tips.
