SOURCE/HOST: Isolated from Latrodectus tredecimguttatus.
QUANTITY: Determined by Lowry and Pierce method.
PURITY: ≥97%
APPEARANCE: White lyophilized powder.
PURITY DETAIL: Migrates as one distinct band when run on a 5-25% gradient polyacrylamide gel according to the method of Laemmli (Nature 227, 680 (1970)).

USE/STABILITY: Stock solution is stable for 1 week when stored at +4°C or for at least one year at -20°C.
HAZARD: POTENT NEUROTOXIN.
Product Description
Causes massive neurotransmitter release from a wide variety of central and peripheral synaptic junctions of vertebrates using Ca2+-dependent and Ca2+-independent pathways. A useful pharmacological tool in the studies of synaptic vesicles exocytosis of different neutrotransmitters.
