Alpha-toxin Amm8 Protein, Androctonus mauritanicus, Recombinant (His & Myc)

Alpha toxins bind voltage-independently at site-3 of sodium channels (Nav) and inhibit the inactivation of the activated channels, thereby blocking neuronal transmission. The toxin principally slows the inactivation process of TTX-sensitive sodium channels. It discriminates neuronal versus muscular sodium channel, as it is more potent on rat brain Nav1.2/SCN2A (EC(50)=29 nM) than on rat skeletal muscle Nav1.4/SCN4A (EC(50)=416 nM). It also shows a weak activity on Nav1.7/SCN9A (EC(50)=1.76 uM). In vivo, the toxin produces pain hypersensibility to mechanical and thermal stimuli.(PubMed:23685008). It also exhibits potent analgesic activity (when injected intraperitoneally), increasing hot plate and tail flick withdrawal latencies in a dose-dependent fashion. This paradoxical analgesic action, is significantly suppressed by opioid receptor antagonists, suggesting a pain-induced analgesia mechanism that involves an endogenous opioid system. This led to hypothesis that pain relief induced by peripheral administration of Amm VIII may result from sensitization of primary afferent neurons and subsequent activation of an opioid-dependent noxious inhibitory control.

缓冲液	If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.
复溶方法	A hardcopy of COA with reconstitution instructions is sent along with the products. Please refer to it for detailed information.
存储	Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
运输方式	In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature. Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
