(Syn. : Alpha-toxin Lqq4, Toxin IV)
Lqq IV | Product ID | L8220-100UG |
| Name | Lqq IV |
| Molecular formula | |
| Description |
It is a toxin purified from Leiurus quinquestriatus hebraeus scorpion venom, presenting 90 % homology in the 20 NH2-terminus residues with Neurotoxin IV from Leiurus quinquestriatus quinquestriatus, a Na+ channel modulator. 65-amino acid polypeptide with 4 disulfide bridges , purified from Leiurus quinquestriatus Hebraeus scorpion venom |
| Biological activity | Alpha toxins bind voltage-independently at site-3 of sodium channels and inhibit the inactivation of the activated channels, thereby blocking neuronal transmission. |
