Product ID L8410-50UG 
Name LATROTOXIN (Alpha-) 
Molecular formula

It is a presynaptic neurotoxin, specific to mammals.

1119-amino acid protein, from Latrodectus (mactans) tredecimguttatus spider venom glands.
Biological activity

In vertebrates, it binds with high affinity to presynaptic membranes. There, it stimulates neurotransmitter release from nerve endings and induces Ca2+ influx. It forms cation selective channels in bilayer and causes fusion of lipid membranes. The biological activity on nerve endings occurs at 10-10-10-9 M.
