Gene Names: N/A
Organism: Centruroides noxius (Mexican scorpion)
AA Sequence: KEGYLVDKNTGCKYECLKLGDNDYCLRECKQQYGKGAGGYCYAFACWCTHLYEQAIVWPLPNKRCS
Expression Region: 17-82aa
Sequence Info: Full Length
Source: E.coli
Tag Info: N-terminal 6xHis-SUMO-tagged
MW: 23.6 kDa
Alternative Name(s): Toxin II.9.2.2
Relevance: Mammal beta-toxins bind voltage-independently at site-4 of sodium channels (Nav) and shift the activation voltage to more negative potentials. This toxin is active against mammals.
Reference: "Solution structure of toxin 2 from Centruroides noxius Hoffmann, a beta-scorpion neurotoxin acting on sodium channels."Pintar A., Possani L.D., Delepierre M.J. Mol. Biol. 287:359-367(1999)
Purity: Greater than 90% as determined by SDS-PAGE.
Storage Buffer: Tris-based buffer，50% glycerol
Storage: The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20℃/-80℃. The shelf life of lyophilized form is 12 months at -20℃/-80℃.
Notes: Repeated freezing and thawing is not recommended. Store working aliquots at 4℃ for up to one week.
