We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.

Relevance
MuO-conotoxins are gating-modifier toxins that inhibit sodium current by trapping the domain II voltage sensor in the closed position to prevent opening of the sodium channel. This toxin has a preference for Nav1.4/SCN4A over Nav1.2/SCN2A sodium channels. It blocks Nav channels by interacting mainly with the C-terminal part of the pore loop of domain-3. It also blocks fast-inactivating calcium current. Blocks Nav1.8/SCN10A sodium channels and has potent and long-lasting local anesthetic effects. It can also block propagation of action potentials in A- and C-fibers in sciatic nerve as well as skeletal muscle in isolated preparations.

Buffer
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.
Purity
Greater than 85% as determined by SDS-PAGE.
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°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
